These attacks constitute clear violations of worldwide humanitarian law and the Convention on Chemical Weapons, the report notes, which the Syrian Arab Republic ratified in 2013 following a previous sarin attack.
In a detailed timeline of a March attack on a mosque in the northern Syrian town of Jinah, the commission said the coalition had neither taken appropriate measures to protect civilians nor provided evidence to back up its claim that the mosque was being used as a meeting place for senior al-Qaida leaders.
GENEVA - U.N. -mandated investigators said Wednesday that Syrian President Bashar Assad's air force conducted a sarin gas attack in the spring that killed at least 83 civilians and sparked a retaliatory US strike.
It said that its strikes in Khan Sheikhoun hit a weapons depot belonging to rebel forces, a claim dismissed by the United Nations investigators.

September 14, 2013: The United States and Russian Federation reach a deal to eliminate Syria's chemical weapons by the middle of 2014, averting punitive U.S. strikes against the regime of President Bashar al-Assad. Following that guarantee, Syria's military dropped chlorine bombs on civilians. While it's true that chlorine has multiple industrial uses, the same can not be said of Sarin gas used in several attacks over the last few years. As it turns out, no matter how much of Syria's stockpile of poison gas the Russians removed, they apparently made sure that there were plenty of weapons left to use on innocent people.
