The UN Security Council on Friday voted unanimously to extend its Syria observer mission by a final 30 days, dpa reported. The mission was extended with the understanding that the observers would assist a transition in Damascus or pull out if no political solution is found to end the 17-month conflict . The Security Council said it could also consider a further extension of the mandate if it could "confirm the cessation of the use of heavy weapons and a reduction in the level of violence sufficient to allow UNSMIS to implement its mandate.
