Braving high costs and temperatures to escape Sudan

STORY: Aisha Ibrahim Dawood is embarking on the last leg of her voyage to safety.

She's among more than 100,000 people, according to the U.N. on Tuesday (May 2), who have fled Sudan's war across borders into its neighbors.

To reach Egypt, Dawood is spending hours in the back of this truck, amid scorching temperatures, with nearly 50 other women and children.

That's after she and her family pooled all their money and jewellery to pay $3,300 to rent a car for the drive from Khartoum to the northern city of Wadi Halfa.

“We would withstand anything. We withstood the sounds of gunfire, we can withstand the heat, this is the simplest thing.”

Sudan's war has now raged for more than three weeks.

Hundreds have been killed and a humanitarian crisis triggered.

Despite a ceasefire deal, gunfire and explosion echoed across the capital on Tuesday.

The U.N. is warning that the conflict risks morphing into a wider disaster as Sudan's impoverished neighbors deal with a refugee crunch.

Here's World Food Programme communications officer Brenda Kariuki.

"The ripple effect for the region is significant. It's a real concern and we just need to find peace. We need the two parties to the conflict to come together and find a way to resolve the conflict because this has the possibility of destabilising the whole region."

Kariuki also warned that a lot of access for humanitarian aid had "suddenly disappeared" in a country where two-thirds of people already relied on some form of outside assistance even before the latest eruption of bloodshed.

The WFP said on Monday (MAY 1) that it had resumed work in safer parts of the country.

That's following a pause in operations earlier in the conflict after some WFP staff were killed.
