Australian government was briefed by the US on the strikes shortly before they began
American-led air strikes against Syria have sent an unequivocal message to the regime of Bashar al-Assad that the use of chemical weapons will not be tolerated, the Australian prime minister, Malcolm Turnbull, has said.
Australia, a staunch ally of the US and a member of the Five Eyes security alliance, was not a part of the attacks on Damascus and Homs, but has issued a statement lending its support to the coalition’s actions. France and the UK joined the US in striking Syrian targets.
