Sudan ceasefire doubts persist despite US announcement.

Warring parties in Sudan have agreed to a 72-hour ceasefire from midnight on Monday, according to US Secretary of State Antony Blinken. This is at least the third ceasefire to be announced since violence erupted this month but none have held. The UN Secretary General has warned the violence in Sudan risks causing a "catastrophic conflagration" that could engulf the whole region and beyond. The ceasefire will hopefully allow civilians to leave the city and foreign governments to continue evacuations out of the country.
