Opposition medics say four people were killed at a demonstration in Omdurman, Sudan on Thursday.
The incident occurred as thousands of demonstrators participated in a “million-man march” to protest the killing of four school children at a rally in El-Obeid earlier this week.
The Central Committee of Sudan Doctors, one of the main protest groups at the event, said there had been some progress in talks with the military on a deal to form a new government after former president Omar al Bashir’s ousting.
Sudan has been gripped by months of political turmoil that climaxed in the army overthrowing the long-time leader in April.
Protesters have kept up their rallies since then, pressing the army to hand over to civilians, accusing the security services of violence and decrying the shortages and economic hardships that triggered the unrest in the first place.
Despite signing a deal in July which secured a three-year transition period and a joint sovereign council with a rotating leadership, talks over the wording of a constitutional declaration on the changes have stumbled.
“The agreement is really now just around the corner,” Satea al-Hajj, a leader in the Forces of Freedom and Change (FFC) coalition of opposition groups, said in a press conference in Khartoum on Thursday.
