Troops fired on demonstrators outside the Sudanese army headquarters, killing at least three people and injuring more than 80, as pro-democracy protesters moved into the streets of the capital, Khartoum, on Monday, after a military coup.
The prime minister was detained, suspending the government and declaring a state of emergency.
The casualty figures was made known by the Central Committee of Sudanese Doctors, and other witnesses reported periodic bursts of gunfire around the city.
The Sudanese ministry of culture and information said on Facebook that military forces had “shot live bullets at protesters rejecting the military coup in Khartoum.”
Schools, banks and business establishments were mostly closed, as the Sudanese Professionals Association, a pro-democracy coalition of trade unions and other groups, called for civil disobedience.
BBC says, the leader of the coup, General Abdel Fattah Burhan, blamed political infighting for the military action.
Civilian leaders and their military counterparts have been at odds since long-time ruler Omar al-Bashir was overthrown two years ago.
Central Bank staff have reportedly gone on strike and across the country, doctors are said to be refusing to work in military run hospitals except in emergencies.
