"Our neighbourhood has become a war zone. There are fierce clashes and strikes all around us because our house is next to the Engineers' Corps," said 45-year-old Jawahir Mohamed.
"We are scared of dying but we are also scared of leaving our house and being burgled," she added.
The fighting has inflicting heavy damage on the capital where the remaining residents are at the mercy of battles, air strikes and looting.
Artillery and air strikes continued overnight, with residents in southern and eastern Khartoum and northern Bahri reporting hearing sounds of artillery and gun clashes on Tuesday morning.
Fighting between the army and paramilitary Rapid Support Forces (RSF), now in its eighth week, has killed hundreds of civilians, and driven 400,000 across borders and more than 1.2 million out of the capital and other cities.
Looters, some of whom Khartoum residents and neighborhood committees say belong to the RSF, have pillaged neighborhoods across the capital, stealing cars, breaking open safes, and occupying homes.
Fighting has expanded beyond Khartoum to the Darfur region to the West, where the RSF originated and maintains a power base. Also hit by fighting is the city of El Obeid, a key route between Khartoum and Darfur.
Aid groups have struggled to provide extensive assistance to Khartoum residents, who face electricity and water shortages as well as dwindling supplies in shops and pharmacies.
Neighborhood-based resistance committees have organised such assistance, but have struggled as fighting has intensified.
"We could not distribute medicines because of the air and artillery bombardment," said one activist who asked not to be named.
