A US Senate panel has approved the use of military force in Syria, in response to an alleged chemical weapons attack.

By 10-7, the Committee on Foreign Relations moved the measure to a full Senate vote, expected next week.

The proposal allows the use of force in Syria for 60 days with the possibility to extend it for 30 days. It prevents the use of US troops on the ground.

President Barack Obama is battling to build support at home and abroad for military action.
