The US is considering air strikes to help the Iraqi government fend off a militant Sunni insurgency in the north, US Secretary of State John Kerry has said.
Mr Kerry said in an interview with Yahoo! News: "They're not the whole answer, but they may well be one of the options that are important."
"When you have people murdering, assassinating in these mass massacres, you have to stop that. And you do what you need to do if you need to try to stop it from the air or otherwise," he added.
The Foreign Secretary has been clear on the threat of Isis, but he has ruled out the prospect of any UK military involvement in the crisis.
Iraq’s foreign minister, Hoshyar Zebari, is a natural diplomat. Polite, immaculately dressed, and blessed with a great memory.
Isis has paraded military equipment in Mosul it captured from when the Iraqi army fled in what some see as a "nightmare scenario."
