There are reports that dozens of people have died in a random shelling of a market in the Sudanese city of Omdurman, however these have not been verified.
On Saturday, 45 people were killed in an air strike in the city, which lies across the River Nile from the capital, Khartoum.
Fighting between the Sudanese army and the paramilitary Rapid Support Forces (RSF) has been going on for three months.
More than 3,000 people have been killed.
