Reuters reports: Government forces have used chemical weapons more than two dozen times during Syria’s civil war, including in April’s deadly attack on Khan Sheikhoun, U.N. war crimes investigators said on Wednesday.

A government warplane dropped sarin on the town in Idlib province, killing more than 80 civilians, the U.N. Commission of Inquiry on Syria said, in the most conclusive findings to date from investigations into that chemical weapon attack.

The panel also said U.S. air strikes on a mosque in Al-Jina in rural Aleppo in March that killed 38 people, including children, failed to take precautions in violation of international law, but did not constitute a war crime.

The weapons used on Khan Sheikhoun were previously identified as containing sarin, an odourless nerve agent. But that conclusion, reached by a fact-finding mission of the Organization for the Prohibition of Chemical Weapons (OPCW), did not say who was responsible.

“Government forces continued the pattern of using chemical weapons against civilians in opposition-held areas.
