An unidentified explosion rocked the neighbourhood of Wadi Al Nasim in the city of Idlib, killing at least 10 civilians and injuring up to 150, local sources said.

Zeiton News said 12 women and seven children were among 29 killed by a long-range ballistic missile launched from Russian battleships. Additional sources, including a military observatory in the region, also reported the use of ballistic missiles by Russian forces.

However, alternative sources said the cause of the explosion could not be identified. Both airstrikes and ballistic missiles from warships in the Mediterranean Sea were reported, while Syria HR raised the possibility of a “booby trapped vehicle explosion.”

The Syrian Civil Defense said the explosion collapsed four residential buildings, including a seven storey building. The headquarters of the Caucasus Army, formerly the Nasra Front, was also damaged. The group belongs to al-Qaeda, according to the Associated Press.
