A former senior intelligence official who worked in Iraq from 2003-2009 has said the US should be considering using 'attack helicopters, special-op forces and drones' in response to the crisis in the country.
Derek Harvey told ITV News that the debate in the US "should be considering a range of things from providing air power, drones and intelligence assistance".
He added: "At the larger end of the spectrum I would hope there is some consideration of putting in some joint task force, that might include some aviation rotary wing assets - both attack helicopter and transportation, along with some special operations forces, intelligence packages."
He added that this would also require medical support and med evac capabilities.
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."
