State-run television in Syria reported that at least 14 people were killed in an explosion at a weapons depot near the city of Sarmada in the northwestern Idlib province.
The broadcaster gave no further details on the identities of those killed or on whether there were additional casualties. Officials have not publicly clarified what caused the blast or released any immediate investigation findings.
There was no independent confirmation of the death toll at the time of the report, and international agencies had not verified the circumstances surrounding the explosion. State media has been the principal source for the casualty figures.
Idlib province has been a focal point of Syria's decade-long conflict and contains numerous military and civilian sites that have been affected by fighting and bombardment. Explosions at storage sites for arms and ammunition have in other conflicts produced large-scale harm to nearby populations and infrastructure, complicating relief and security operations.
Authorities have not announced any measures taken in response to the blast, and it remained unclear whether local emergency services or national agencies were conducting search, rescue or containment efforts.
