DAMASCUS: Syrian authorities have arrested three brothers accused of taking part in the mass execution of 15 civilians during the rule of former President Bashar Assad, with investigators citing video footage they say documented the killings, state news agency SANA reported on Saturday.

The Interior Ministry identified the suspects as Akram, Farzat, and Ghiyath Shamma.

It said investigations, supported by witness testimony and video footage, concluded that the three men detained 15 civilians before executing them during the 2014 uprising against the former government.

A video captured the victims with their hands tied and eyes blindfolded after being forced at gunpoint to praise the former regime before being shot, the ministry said.

The suspects acknowledged appearing in the video, according to the statement.
