An explosion crater filled with water and rubbish in Mariupol on 29 April

The Ukrainian port city of Mariupol, all but destroyed by weeks of shelling and now under Russian control, is at risk of a major cholera outbreak, the UK defence ministry says. 

Much of the city's infrastructure is damaged or destroyed and water has mixed with sewage, according to the UN. 

Cholera is usually caught by eating or drinking contaminated food or water and is closely linked to poor sanitation. 

Uncollected dead bodies and rubbish add to the unsanitary conditions. 

There have been outbreaks of the disease in Mariupol before, and isolated cases have been reported in the past month. 

The logo of the new Russian restaurant chain after McDonald's left the country

The Russian fast food chain that was formerly McDonald's in the country has revealed its new logo as it prepares to reopen its restaurants from Sunday.

The new branding features a circle and two lines, which are said to represent a burger and two French fries.

The company has not yet revealed the name of the chain, although a number of options have reportedly been considered.

In May, McDonald's said it would pull out of Russia over the Ukraine war.

Aiden Aslin, Shaun Pinner, and Moroccan national Saaudun Brahim were sentenced to death by a Russian proxy court

The families of two Britons sentenced to death for fighting Russian forces in Ukraine have said the pair need urgent access to medical and legal help.

Aiden Aslin and Shaun Pinner were captured fighting with the Ukrainian army and tried as mercenaries by a Russian proxy court.

Both the UK government and Ukraine's top prosecutor say the sentences breached the Geneva Conventions.

The UK's Prime Minister Boris Johnson urged ministers to do "everything in their power" to secure their release.
