Obama: 'We need to push IS back'

President Barack Obama has said the deployment of 1,500 more US troops to Iraq marks a "new phase" against Islamic State militants.

He told CBS TV that the new troops, although non-combat advisers, could help Iraq go on the attack against IS.

In his interview with CBS's Face the Nation broadcast, Mr Obama said: "Phase one was getting an Iraqi government that was inclusive and credible - and we now have done that.

"Now we need Iraqi ground troops to start pushing them back," he said.
