More than 200 people have been killed in gang violence in Haiti's capital, Port-au-Prince, in the space of 10 days, United Nations figures reveal.

Almost half of those who died were residents without ties to the gangs which are fighting for control of the Cité Soleil neighbourhood, the UN says. Locals say they are running out of drinking water and food as deliveries have been halted amid the shoot-outs. One resident described his life as "a cycle of fear, stress and despair".

Gang violence had already shot up since the assassination of President Jovenel Moïse by mercenaries a year ago, but it has reached shocking new levels since a battle erupted on 8 July between two criminal alliances, known as G9 and G-Pèp. The UN says that 209 people were killed between 8 and 17 July, of which 114 were gang members. A further 254 people have sustained gunshot wounds, more than half of them residents without links to the gangs.

Coordinated suicide bomb blasts at Kabul airport on Thursday have left at least 170 dead and many more injured.

Isis-K has claimed responsibility for the attack, which targeted US troops and Afghans attempting to secure the last remaining places on military evacuation flights out of the country.

On Friday, the US said it killed a "planner" for the group in an air strike in Afghanistan.

The threat of further attacks around Kabul Airport will increase as Western troops get closer to leaving the country, Defence Secretary Ben Wallace said on Friday, with Isis-K hoping to show it drove foreign troops from Afghanistan.

"The threat is obviously going to grow the closer we get to leaving," he told Sky News. "The narrative is always going to be, as we leave, certain groups such as ISIS will want to stake a claim that they have driven out the US or the UK." 

On Thursday night, President Joe Biden pledged to "hunt down" the attackers and ordered his military to plan strikes.

He said: "Know this: we will not forgive, we will not forget. We will hunt you down and make you pay." 

Here we look at how Isis-K came to exist and why it poses such a threat to US forces in Afghanistan. 

At least 47 people, including 30 civilians and 14 soldiers, killed by rebels in Arbinda town, according to state media.

Rebel fighters have killed dozens of people in northern Burkina Faso, as violence spirals anew in West Africa’s Sahel region.

In an attack near the northern town of Arbinda on Wednesday, rebels killed at least 47 people, including 30 civilians, 14 soldiers and three pro-government militiamen, state media reported.

State media reported that government troops killed 16 rebels while a security source put the number at 58.

Fighters linked to al-Qaeda and ISIL regularly carry out attacks in Burkina Faso and neighbouring Mali and Niger, killing hundreds of civilians this year alone.

Violence in the Sahel, a semi-arid band beneath the Sahara Desert, has continued to intensify despite the presence of thousands of UN, regional and Western troops and efforts by some governments to negotiate with rebel groups.

Ivory Coast’s first Ebola case since 1994 was discovered over the weekend in an 18-year-old Guinean woman.

Guinean authorities say 58 people have been confined to their homes after being identified as contacts of a woman who contracted the Ebola virus.

The Ebola case was discovered in Ivory Coast in an 18-year-old Guinean woman who had travelled by bus from Labe, Guinea, a journey of some 1,500km (930 miles).

It was Ivory Coast’s first known case of the disease since 1994.

Ebola is often deadly, causing severe fever and, in the worst cases, unstoppable bleeding. It is transmitted through close contact with bodily fluids, and people who live with or care for patients are most at risk.

The discovery in Ivory Coast came nearly two months after the United Nations’ health agency declared an end to Guinea’s second Ebola outbreak, which started last year and killed 12 people.

Intense fighting is being reported in Ethiopia's Amhara state - the latest sign that the war that erupted in the Tigray region in November is spreading.

Federal forces as well as Amhara regional troops were involved in fighting Tigray rebels on three fronts, an Amhara official told the BBC. This is despite the government saying a unilateral ceasefire declared last month had not been suspended. All sides have accused each other of escalating the conflict.

The situation has intensified since the Tigray People's Liberation Front (TPLF) rebels recaptured much of Tigray in a spectacular offensive against the national army in June.
