Sudan: US-Saudi brokered ceasefire begins with reports of continued fighting

Deal to stop violence comes as journalists' syndicate accuses paramilitary group of targeting reporters

A weeklong ceasefire in Sudan intended to allow the delivery of humanitarian aid got off to a shaky start on Monday evening as witnesses in the capital, Khartoum, reported fighter jets over the city and continued fighting in some areas.

The US and Saudi Arabia announced the deal to stop six weeks of fighting, saying it would come into force at 9.45pm (7.45pm BST). World powers had put pressure on the army and the rival paramilitary Rapid Support Forces to sign a deal. Previous attempts have fallen apart.
