The World Health Organization also notes that some 60% of health facilities in Khartoum are currently not operating and they expects disease to spread and more deaths to occur due to the lack of basic services.

The head of the Norwegian Refugee Council in Sudan has told the BBC the situation in the capital, Khartoum is devastating.

"This conflict, this heavy urban warfare and airstrikes, to be honest relentlessly through the last couple of weeks, has not just damaged critical infrastructure and of course people's houses, but it is beginning to cause the collapse of the markets and social systems there," Will Carter told the BBC's Newsday programme.

“No healthcare, no power, no fuel, no water, no banking, very little phone or data coverage. It's beginning to crumble there and it's a very desperate situation for the millions of people still trapped," he added

Hundreds of people have been killed and thousands others wounded in the clashes between rival military forces.
