"IS will lose" - President Obama

Thursday, 12 February 2015 - 8:03

President Barack Obama has said Islamic State militants "will lose" as he asks Congress to formally authorise military force against them.

He warned against dragging the US into another prolonged ground war and called on lawmakers to show a united front.

The US has carried out air strikes against IS since last year, in a coalition with other nations.

It's the first time a US president has sought Congressional approval to use military force since President George W Bush in 2002, ahead of the invasion of Iraq.
