Air strikes hit outer areas of the Sudanese capital Khartoum overnight and on Saturday morning, as fighting that has trapped civilians in a humanitarian crisis and displaced more than a million entered its sixth week.

The fighting between Sudan's army and the paramilitary Rapid Support Forces (RSF) has led to a collapse in law and order that the two sides blame the other for. Stocks of food, cash and essentials are rapidly dwindling, and mass looting has hit banks, embassies, factories and aid warehouses.

Air strikes were reported by eyewitnesses in southern Omdurman and northern Bahri, the two cities that lie across the Nile from Khartoum, forming Sudan's "triple capital". Some of the strikes took place near the state broadcaster in Omdurman, the eyewitnesses said.

"We faced heavy artillery fire early this morning, the whole house was shaking," Sanaa Hassan, a 33-year-old living in the al-Salha neighbourhood of Omdurman, told Reuters by phone.

"It was terrifying, everyone was lying under their beds. What's happening is a nightmare," she said.

The RSF is embedded in residential districts, drawing almost continual air strikes by the regular armed forces.

Eyewitnesses in Khartoum said that the situation was relatively calm, although sporadic gunshots could be heard.

The conflict, which began on April 15, has displaced almost 1.1 million people internally and into neighbouring countries. Some 705 people have been killed and at least 5,287 injured, according to the World Health Organization.
