Veteran UN peacekeeper Major-General Robert Mood has arrived in Damascus, flying in to what's become a very fragile peace.
The two week old ceasefire has been violated every day with bloodshed on both sides.
CNN's Mohammed Jamjoon reports it's a very tenuous situation.
"It appears to be unravelling. Now roughly 30 monitors are expected to be on the ground by Monday and a total of about 300 are supposed to arrive in the coming months but there's growing concern that no matter the amount of monitors that get there, the violence is going to continue."
The Major-General has negotiated with Syrian authorities the conditions for the deployment of an advance team, but he's already said unarmed peacekeepers are not going to be able to control the situation.
He has realistic expectations.
"Even 1.000 unarmed observers cannot solve all the problems."
