Syrian opposition claims to have solid evidence for Syrian government and ISIS cooperation.
A Syrian opposition member, colonel Fateh Hassoun who take part of the Geneva peace talks, claimed that the delegation had indisputable facts that the Syrian government is involved with ISIS.
For example that is fact that the Syrian Army relinquished control of Palmyra to ISIS. “The file will be handed over to the United Nations,” Hassoun said.
As well as collaboration included “close cooperation and coordination” between the government and ISIS, particularly in Homs.
