The US "is not going to be the only tool in the toolbox" that can be used in the fight against Islamic State, the Pentagon press secretary has said.
Speaking at press briefing, Rear Admiral John Kirby stressed that an "international approach" was needed to deal with the Islamist militant group.
But he warned that a "multi-lateral and multi-national approach" to dealing with the threat "will take time to develop."
"I think we all recognise that this group didn't grow up overnight, they didn't get the capabilities that they got overnight - we've been watching them for a while," he added.
