Ukrainian army says immediate clashes have broken out on the streets of Ukraine’s second city after landing of Russian paratroopers.

The Ukrainian military says immediate clashes have erupted after Russian paratroopers landed in Ukraine’s second largest city of Kharkiv on the seventh day of Russia’s full-scale invasion of its neighbour.

“Russian airborne troops landed in Kharkiv … and attacked a local hospital,” the army said on Wednesday, in a statement on the Telegram messaging app. “There is an ongoing fight between the invaders and the Ukrainians.” According to Anton Gerashchenko, adviser to the Ukrainian interior minister, a fire broke out on Wednesday in the barracks of a flight school in the city following an air raid. “Practically there are no areas left in Kharkiv where an artillery shell has not yet hit,” he said in a statement posted on Telegram.

The city’s governor, Oleg Synegubov, also said on Telegram that seven people were killed in an attack on a government building and that 24 people were wounded. The reports could be independently confirmed. Russia says it is only targeting Ukraine’s military infrastructure, air defence and air forces with high-precision weapons.

Russia claims control of southern Ukrainian city of Kherson

Defence ministry says talks are under way between Russian army and local authorities on maintaining order. The Russian army has claimed it has taken control of the strategically important city of Kherson in southern Ukraine as Moscow’s invasion of the country entered its seventh day. “The Russian divisions of the armed forces have taken the regional centre of Kherson under full control,” defence ministry spokesman Igor Konashenkov said in televised remarks on Wednesday.

He claimed that public services and transport were operating as usual. “The city is not experiencing shortages of food and essential goods,” he said. He added that talks were under way between the Russian army and local authorities on maintaining order, protecting the population and keeping public services functioning.

Kherson’s Mayor Igor Nikolayev, however, said in a post on Facebook: “We are still Ukraine. Still firm.”

Apparently contradicting the Russian army’s claims, he said he needed to find a way to “collect the [bodies of the] dead” and “restore electricity, gas, water and heating where they are damaged”. “But I warn you right away: To complete these tasks today means to perform a miracle,” he added.

A Russian invasion of Ukraine could happen at any moment, a defence minister has warned.

Armed Forces Minister James Heappey has described the massing of roughly 130,000 Russian troops along the Ukrainian border as a "credible force set to do something imminently".  It comes after Defence Secretary Ben Wallace compared diplomatic efforts to prevent a Russian invasion of Ukraine to appeasement as he said it is "highly likely" Vladimir Putin will order an attack despite the concerted talks to avert war.

China has joined Russia in opposing further Nato expansion as the two countries move closer together in the face of Western pressure.

Moscow and Beijing issued a statement showcasing their agreement on a raft of issues during a visit by Russia's Vladimir Putin for the Winter Olympics. Mr Putin claims Western powers are using the Nato defence alliance to undermine Russia.

It comes amid tensions over Ukraine, which he denies planning to invade. Some 100,000 Russian troops remain at the border with Ukraine, which is a former Soviet republic. Mr Putin, who has written that Russians and Ukrainians are "one nation", has demanded that Ukraine be barred from joining Nato. While the lengthy joint statement did not refer directly to Ukraine, the two countries accused Nato of espousing a Cold War ideology.

The talks, which the Kremlin said were "very warm", were held ahead of the Games opening ceremony. It was the first time the leaders have met face-to-face since the start of the pandemic. "Friendship between [Russia and China] has no limits, there are no 'forbidden' areas of cooperation,"

The UK Defence Secretary said there were individuals already in Ukraine "linked to the Russian state in ways that are not conventional".

Russia may already have personnel in place in Ukraine to assist with an invasion, the UK Government believes. Defence Secretary Ben Wallace told MPs there were individuals already in Ukraine "linked to the Russian state in ways that are not conventional" and "that should give cause for concern". He added: "We are becoming aware of a significant number of individuals that are assessed to be associated with Russian military advance force operations that currently are located in Ukraine."

It comes as concerns over a potential Russian invasion into Ukraine continue to increase. Moscow has massed an estimated 100,000 troops near the border with Ukraine. Mr Wallace told the Commons Foreign Affairs Committee that any incursion into Ukrainian territory would be unacceptable. He said: "Any crossing into Ukraine, whether small or large, would be viewed as a breach of that sovereignty, against international law and an invasion. "You can't be half-pregnant, you are either invading a country or you are not."

Hostilities have simmered for years but tensions are now escalating amid fears of a Russian invasion.

Kyiv, Ukraine – According to Washington, Russia has amassed more than 100,000 Russian soldiers on the border with Ukraine and in annexed Crimea in recent weeks.

This has stoked fears in Kyiv and the West that the Kremlin may start a new war with its neighbour and former province that chose to break away from Moscow’s political orbit.

Earlier this month, a top Ukrainian military expert told Al Jazeera that Russia could invade Ukraine as early as January, unleashing a “brief and victorious” war. But Russia denies it is planning an invasion. Moscow says it can move Russian troops wherever it wants and that any of its acts are defensive. Russian officials, including President Vladimir Putin, have for their part warned NATO against expanding eastwards. So, what is at the heart of the conflict that has been going on for more than seven years?

What is now Ukraine, Russia and neighbouring Belarus were born on the banks of the Dnieper River, almost 1,200 years ago in Kievan Rus, a medieval superpower that included a huge chunk of Eastern Europe. But Russians and Ukrainians parted ways linguistically, historically and, most importantly, politically.

Putin has, however, claimed repeatedly that Russians and Ukrainians are “one people”, part of the “Russian civilisation” that also includes neighbouring Belarus. Ukrainians reject his claims. Ukraine went through two revolutions in 2005 and 2014, both times rejecting Russia’s supremacy and seeking a path to join the European Union and NATO. Putin is particularly enraged by the prospect of NATO bases next to his borders and says Ukraine joining the US-led transatlantic alliance would mark the crossing of a red line.

US President Joe Biden has said he thinks his Russian counterpart Vladimir Putin will "move in" on Ukraine but does not want "full-blown war".

He told a news conference Mr Putin would pay a "serious and dear price" for invading, but indicated a minor incursion might be treated differently. The White House later stressed any Russian military move would be met with a swift, severe response from the West.

Russia has some 100,000 troops near the border but denies planning an invasion. President Putin has made a series of demands to the West, insisting Ukraine is never allowed to join Nato and that the defensive alliance abandons military activity in Eastern Europe.

Talks between the West and Russia have so far failed to reach a breakthrough, with some of Moscow's demands rejected as non-starters. US Secretary of State Antony Blinken is due to meet the Russian foreign minister in Geneva on Friday, having warned that Russia could attack Ukraine "on very short notice". However, at his news conference on Wednesday, Mr Biden said: "There are differences in Nato as to what countries are willing to do, depending on what happens. "If there's Russian forces crossing the border… I think that changes everything.

"What you're going to see is that Russia will be held accountable if it invades and it depends on what it does," he said. "It's one thing if it's a minor incursion, and then we end up having to fight about what to do and not do etc."

White House officials rushed to clarify the US position after Mr Biden's comments. "If any Russian military forces move across the Ukrainian border, that's a renewed invasion, and it will be met with a swift, severe, and united response from the United States and our Allies," press secretary Jen Psaki said. Hours earlier, French President Emmanuel Macron told the European Parliament that Europeans had to conduct their own dialogue with Moscow.

Security forces in Kazakhstan say they have killed dozens of anti-government rioters in an operation to restore order in the main city, Almaty.

They moved in after protesters tried to take control of police stations in the city, a police spokeswoman said. Twelve members of the security forces have been killed and 353 injured in the unrest, sparked by a doubling in the cost of liquefied petroleum gas (LPG).

Russia is sending in troops at the request of the Kazakh president. They will be deployed to help "stabilise" the country, which is a member of the Collective Security Treaty Organisation (CSTO) along with Russia, Belarus, Tajikistan, Kyrgyzstan and Armenia. The CSTO confirmed Russian paratroopers were being dispatched as peacekeepers, with advance units already deployed, and footage released by Russian media showed soldiers boarding a military transport plane.

Protests began on Sunday when the government lifted its price cap on LPG, which many people use to fuel their cars, but the unrest has since spread to include political grievances. Accusing foreign-trained "terrorist gangs" of being behind the trouble, President Kassym-Jomart Tokayev imposed a nationwide state of emergency that includes a curfew and a ban on mass gatherings.

Sixteen European governments have issued a statement to "firmly condemn the deployment of mercenary troops" in the west African state of Mali.

The 16 governments, including France, the United Kingdom, Italy and Germany, said they were aware of "the involvement of the Russian Federation government in providing material support to the deployment of the Wagner group in Mali and call on Russia to revert to a responsible and constructive behavior in the region."

The exercises, involving ground troops and air forces, come amid growing instability in Afghanistan.

Chinese and Russian military forces are engaged in joint exercises in north-western China as ties grow between the two autocratic states amid uncertainty over instability in Afghanistan.

The exercises involving ground troops and air forces are due to continue through until Friday in the Ningxia Hui Autonomous region.

The region borders on Xinjiang, where China has detained more than one million Uyghurs and members of other Muslim minorities in what it calls a campaign against terrorism and extremism.

Xinjiang shares a narrow frontier with Afghanistan, and Beijing is concerned about violence spilling over its border if the Taliban take control in the country following the pullout of US and NATO troops.

While not part of a formal alliance, Russia and China have aligned their military and foreign policies largely in opposition to those of the US and its allies.

The official Xinhua News Agency said the exercises began on Monday and were presided over by Li Zuocheng, a member of the ruling Communist Party's Central Military Commission.

The exercise aims to "deepen the joint anti-terrorism operations between the Chinese and Russian militaries and demonstrate the firm determination and strength of the two countries to jointly safeguard international and regional security and stability", Xinhua said, citing Chinese and Russian officials.

"It reflects the new height of the China-Russia comprehensive strategic partnership of co-ordination for a new era and of the strategic mutual trust, pragmatic exchanges and co-ordination between the two countries," Xinhua said.

Russia has backed China in its claim to virtually the entire South China Sea, over which Beijing clashed with common rival the US at a high-level UN Security Council meeting on maritime security.

Beijing has been accused of sponsoring an attack on Microsoft Exchange email servers earlier this year which "recklessly" exposed thousands of businesses to criminal hackers.

The Chinese government has been accused of "systematic cyber sabotage" in statements by the UK and allies, including the US and Canada.

The allies are announcing that they believe Chinese state-sponsored hackers were responsible for an attack earlier this year which "indiscriminately" compromised an estimated 400,000 servers worldwide, leaving them exposed to criminals.

More than 70 organisations in the UK were compromised by the hack, perpetrated by a group associated with Beijing according to the National Cyber Security Centre. This attribution has been supported by allies.

Foreign Secretary Dominic Raab described the hacking campaign - which is believed to have compromised the on-premise email servers indiscriminately with an intention to subsequently target specific victims - as "a reckless but familiar pattern of behaviour" from the Chinese government.

The head of MI5 is to urge the public to be as vigilant about threats from "hostile states" as from terrorism. These include disruptive cyber-attacks, misinformation, espionage and interference in politics - and are usually linked to Russia and China.

In a speech on Wednesday, Ken McCallum will say these "less visible threats... have the potential to affect us all". He will say these threats are affecting UK jobs and public services and could even lead to a loss of life.

The head of the Security Service wants to challenge the idea that activity by so-called "hostile states", usually taken to mean primarily Russia and China, only affects governments or certain institutions. Instead, he will argue, in an annual threat update, that the British public are not immune to the "tentacles" of covert action by other states.
