Sudan's latest ceasefire now appears to be holding despite early breaches of the deal.
It's the first truce to have been formally agreed and signed by both sides, but there were reports of airstrikes and clashes in the capital Khartoum as it came into force on Monday evening.
In the cities of Omdurman and Bahri which adjoin the capital, people said they'd heard gunfire.
The ceasefire will enable the delivery of badly needed humanitarian aid.
Hours before the latest truce was due to begin, the head of the paramilitary RSF, General Hamdan Dagalo, issued a belligerent statement urging his troops to defeat the national army and win the war.
