The warring sides in Sudan have accused each other of being behind breaches of the latest ceasefire, now in its third day.
The one-week truce was violated minutes after it came into effect on Monday night, with residents of the capital, Khartoum, witnessing air strikes and artillery fire.
Sporadic clashes between the army and a paramilitary group, the Rapid Support Forces (RSF), have spilled over into Thursday.
But the current ceasefire has allowed some residents to venture out of their homes for food, water and medical care.
The conflict has exacerbated an existing humanitarian crisis, forced more than 1.3 million people to flee and threatened to destabilise the region.
