The advance team of UN observers toured several suburbs of Syria's capital Damascus on Monday, mainly the resort town of Zabadani near Lebanese borders, which has emerged as a scene of armed insurgency, the team's spokesman Neeraj Singh told Xinhua.

However, the spokesman did not disclose further details on the visit.

A day earlier, the team visited two regions in central Syria and "established liaison with all parties there."

The UN Security Council on Saturday unanimously decided to approve the deployment to Syria of up to 300 unarmed UN military observers in order to monitor a fragile ceasefire between Syrian government forces and armed opposition fighters.

Meanwhile, Singh said the task that has been assigned to UN observers is to establish liaison between all the parties and make logistic arrangements. "We are in the process of receiving more military observers and we expect them tomorrow and within the next few days," he said.

On the ground, seven unarmed military observers are already in place, two of whom were dispatched to Homs on Saturday. Many more are expected to arrive in Syria by next week.

The observers in Homs visited al-Waer neighborhood on Monday, Syria's state-run SANA news agency reported.

The advance team of international observers arrived last week after Syria accepted the UN-backed truce aiming to solve the crisis politically.

Since their arrival, violence has to some extent declined, but attacks and deaths are reported to be taking place on a daily basis.
