US Secretary of State Rex Tillerson said that there would not be military cooperation between Washington and Moscow until Russian accepted that not all the opposition are terrorists.
Tillerson had stressed that Moscow's position to align itself with the Syrian government to label all rebels as terrorists would make military cooperation between Washington and Moscow complicated.
"In the discussion, he made it clear that there would not be military cooperation until the Russians accepted that not all the opposition are terrorists," Reuters cited Rex Tillerson as saying.
