Western allies are gearing up for possible military intervention in Syria.

The UN weapons inspectors haven’t finished their investigation of an alleged chemical weapons attack on civilians in Damascus. In fact, they have delayed their second attempt until tomorrow after being fired on by unknown snipers yesterday.

US President Barack Obama is expected to announce his country’s response today. Secretary of State John Kerry says the US is convinced that the regime of President Bashar al-Assad is responsible for firing chemical weapons on its citizens.

British Prime Minister David Cameron has also recalled Parliament to discuss the crisis.

Meanwhile, the Syrian Foreign Minister says his country will defend itself “by all means available” in the even of an attack.
