The SOHR said regime ally Russia "likely" carried out the air strikes on a planned buffer zone around the opposition bastion of Idlib, the first to hit the area since Moscow and rebel backer Ankara agreed to set up a demilitarised area around Idlib to prevent a massive regime attack to retake the area.
