Dozens of pro-government troops were killed when militants blew up a tunnel underneath a building in the Syrian city of Aleppo, BBC reported on Friday, citing reports of a UK-based monitoring group.
According to the reports, the blast killed 38 troops on Thursday.
The Thuwwar al-Sham militant group published online a video showing the process of the destroying of the building. The footage showed members of the group planting explosives inside the tunnel, and the building blowing up in a huge explosion in a cloud of rubble and ash.
Initially, according to the Syrian Observatory for Human Rights (SOHR), 14 people were killed by the tunnel bomb. However, on Friday, SOHR revised this upward.
Aleppo has been divided between the militant-held east and government west for the past four years. Hundreds of thousands of people live in the east of the city, which was effectively cut off by government forces earlier this month. The military campaign of the government forces against the city’s militant-held areas have been intensified with the support of Russian air strikes in recent weeks.
