DAMASCUS, Syria: At least three trucks bringing food and medicine to a besieged Syrian town near the Lebanese border have entered the town.

The humanitarian aid to Madaya, blockaded by government troops and their allies for months, is part of a large-scale UN-supported aid operation in the war-ravaged country.

An aid convoy is to simultaneously enter the Shiite villages of Foua and Kfarya in Idlib province, under siege by rebels seeking to oust President Bashar Assad.

An Associated Press crew on the outskirts of Madaya said three trucks crossed into the town Monday evening.
