At least 39 people were killed on Sunday, including children, by an explosion at a weapons depot in the Idlib village of Sarmada, said the UK-based Syrian Observatory for Human Rights.
The Syrian Civil Defense, first responders better known as the White Helmets, put the death toll at 36 people, but noted that it could be higher since rescue operations were ongoing.
The depot had been housed in a residential building, said the independent war monitor, which uses a vast network of on-the-ground sources. The explosion caused two five-story buildings to collapse, according to local activists.
“Rescue and firefighting teams are still working to pull out other victims from under the rubble,” a civil defense volunteer told DPA news agency.
