Security forces in Sudan have used live ammunition to disperse protesters in the capital, Khartoum.
The Central Committee of Sudanese Doctors, a medical group affiliated with the protesters said 13 people have been killed and hundreds injured.
Protesters have been staging a sit-in for several weeks now, demanding an end to military rule since the fall of Omar al-Bashir in April.
The Sudanese Professionals Association, the group leading the protests said, “The protesters holding a sit-in in front of the army general command are facing a massacre in a treacherous attempt to disperse the protest.”
Mohammed Alamin, a journalist in Khartoum said that the Rapid Support Forces (RSF) first used tear gas, then sound grenades to disperse the protesters before firing live rounds at the remaining protesters.
News of the military operation has sparked unrest in neighbouring city, Omdurman with thousands of protesters blocking roads with stones and burning tyres.
The military operation came after Sudanese military leaders called the sit in “a danger” to Sudan’s national security and warned that action would be taken against what they called “unruly elements."
An alliance of protest and opposition groups said it was halting all contact with the Transitional Military Council (TMC). The two sides have been in talks for weeks over who should govern the sovereign council, the highest decision-making body in the transition period.
