The head of the UN observer force has accused both sides in the Syrian conflict of hampering its mission.
Major General Robert Mood told a news conference in Damascus that it was the Syrian people who were suffering the consequences of the failure to implement UN-Arab League envoy Kofi Annan's peace plan.
He said both sides are pushing towards military advances rather than a peaceful transition.
"Violence, over the past 10 days, has been intensifying, again willingly by both the parties, with losses on both sides and significant risks to our observers," he said.
The mission's mandate will be reviewed by the UN Security Council at the end of July.
"It is important that the parties give this mission a chance," said Major General Mood.
