A United Nations advance observers' team arrived in the Syrian capital of Damascus late Sunday to monitor the cease-fire brokered by international envoy Kofi Annan, sources told Xinhua anonymously.
The arrival of the six-member advance team came a day after the UN Security Council unanimously approved the observers' mission. The team will be backed with other batches of observers over the next period, and the total number of observers may eventually reach 250.
The observers' mission came as part of the six-point plan by Annan that meant to solve the Syrian crisis politically.
The plan calls for a troop withdrawal from populated areas by April 10 and a cease-fire by April 12, and also calls for allowing in foreign media and peaceful demonstrations.
Syria has officially agreed on the plan and observed a cease- fire that went into effect last Thursday.
Violence and death toll have to some extent declined in comparison with the previous stage, but small-scale clashes and attacks were still being reported during the fragile four-day-old truce.
