Iran’s militias were behind the chemical attack targeting Aleppo, and they seek to abort the Sochi deal in Idlib, the head of the High Negotiations Committee, Naser al-Hariri, told al-Hadath news channel. The High Negotiations Committee is an umbrella body which was created to represent the Syrian opposition in the planned Geneva peace talks in 2016. This comes after government shelling killed nine people on Saturday in Syria’s rebel-held Idlib, while state media said insurgent shells wounded dozens in Aleppo causing breathing problems. The deal to create the demilitarized zone staved off an army offensive against the Idlib region, including nearby parts of Aleppo and Hama provinces. Earlier this month, Moscow accused insurgents of trying to wreck the deal, while rebels accused the Syrian army and its allies of attacking the region.
