Sudan's doctors union says 57 killed in recent protests

Sudan's Doctors Syndicate says the government crackdown on protests has left at least 57 dead, including three who died of torture, since they began in mid-December.

In a statement issued on Friday, the union said that the death toll is expected to climb because of the serious condition of some wounded protesters.

It also noted the excessive use of tear gas in the crackdown, including in residential areas, and inside homes and hospitals.

Additionally, it expressed its alarm at security forces using the "inconceivably barbaric tactic" of running over protesters while breaking up demonstrations, according to the statement.

A total of 28 doctors have been detained, and one doctor was shot dead for treating wounded protesters, it added.

The statemen cames one day after a chief investigator concluded that an iconic protester Ahmed al-Khair was beaten to death while in custody.
