At least 40 people, including children, have been reported killed in a car bomb blast in Syria, outside a mosque in a town in Damascus province, BBC reported.
The blast, in the town of Suq Wadi Barada, came just before the end of Friday prayers and brought down the mosque's entrances.
Both the government and rebels blamed each other for the explosion.
Meanwhile, Norway has turned down a request to help the UN dismantle Syria's chemical weapons arsenal.
The UN has set a deadline of mid-2014 for the weapons to be destroyed.
Sweden has offered to provide an air force unit to transport the weapons. But Norway, asked by the US to help destroy the arms, said it was "not the most suitable location" for the work.
