Sudanese flee homeland as airstrikes threaten ceasefire | First Thing

Long lines are forming at the borders as people fleeing fighting around the capital face daylong waits and demands for visas in order to cross to safety

Good morning.

The UN's refugee agency said it was expecting 270,000 refugees to cross into Chad and South Sudan as airstrikes and reports of renewed fighting around the capital have threatened a delicate three-day truce.

The UN secretary general, Antonio Guterres, has warned that the fighting is not only putting Sudan's future at risk, it is lighting a fuse that could detonate across borders, causing immense suffering for years, and setting development back by decades".

Those who have escaped the violence in Khartoum are sharing harrowing tales of being forced to hole up in homes for days, bullets flying through kitchen windows and threats from soldiers with guns.
