At least 32 civilians have been killed and dozens injured in artillery attacks by the Sudanese army, one of the highest tolls from a single day of fighting since war broke out in April, the activist group Emergency Lawyers said.

The shelling on Tuesday took place in the Ombada neighbourhood in western Omdurman, the statement released on Wednesday said, a neighbourhood that has seen several deadly attacks.

Rights activists and residents said that the regular army and the paramilitary Rapid Support Forces (RSF) that are fighting for control of the country have fired missiles into populated areas, incurring hundreds of civilian casualties in the capital Khartoum and other cities.

While the RSF holds most of the ground in Khartoum and the cities of Omdurman and Khartoum North that make up the wider capital, the army has the edge in heavier artillery and aircraft.
