A Senate panel has voted to give US President Barack Obama the authority to use military force against Syria in response to a deadly chemical weapons attack.
The vote was 10-7. The full Senate is expected to vote on the measure next week.
The resolution would permit Mr Obama to order a limited military mission against Syria, as long as it does not exceed 90 days and involves no American troops on the ground for combat operations.
The Democratic chairman of the Foreign Relations Committee, Senator Bob Menendez, and the panel's top Republican, Senator Bob Corker, crafted the resolution.
The vote marked the first time US politicians have voted to authorise military action since the October 2002 votes giving President George W Bush the authority to invade Iraq.
