As explosions and gunfire thundered outside, Sudanese in the capital Khartoum and other cities huddled in their homes for a third day Monday, while the army and a powerful rival force battled in the streets for control of the country.

At least 185 people have been killed and over 1,800 wounded since the fighting erupted, UN envoy Volker Perthes told reporters. The two sides are using tanks, artillery, and other heavy weapons in densely populated areas. Fighter jets swooped overhead, and anti-aircraft fire lit up the skies as darkness fell.

The toll could be much higher because there are many bodies in the streets around central Khartoum that no one can reach because of the clashes. In central Khartoum, sustained gunfire erupted and white smoke rose near the main military headquarters, a major battlefront.

Outbreak of violence between nation’s two top generals, each backed by tens of thousands of heavily armed fighters, trapping millions of people in their homes as supplies run low
