At least four school children and one adult were shot dead as security services broke up a protest in the Sudanese city of El-Obeid.
According to a group of doctors linked to the opposition the five were hit during a demonstration by high school pupils in the main city in Sudan’s North Kordofan state.
The Central Committee of Sudanese Doctors further said that many other people were injured.
There was no immediate statement from the state security services, or from Sudan’s military leaders who ousted Bashir in a coup in April as the protests mounted.
Videos circulating on social media purported to show pupils protesting outside El-Obeid’s main hospital against the killings and injuries.
Hundreds of teenagers in uniform chanted “blood for blood, we will not accept blood money” in the footage. Reuters could not immediately verify the authenticity of the videos, or when they were taken.
The doctors group did not give details the genesis of the protests in El-Obeid, around 400 km southwest of the capital Khartoum.
However, opposition activists have kept up their demonstrations since April, pressing for the military to speed up the move to civilian rule and calling for justice for people killed during a raid on a sit-in protest in Khartoum in June.
The main opposition Forces of Freedom and Change coalition is negotiating with the ruling military council to finalize an agreement for a three-year transition to elections.
The two sides signed a deal on July 17 but have since disagreed on the wording of a constitutional declaration to determine the role of a new council to run Sudan.
