"When we talked about all the methods, we also meant the military one. We will not rule out the military option," Muallem said at a joint press conference with his Venezuelan counterpart Jorge Arreaza.

"We are fighting with terrorists, as it is proved that they cooperate with Israel and the US. Today, our priority is the struggle for the liberation of Syrian territory from this terrorism," Muallem said.
