Video has emerged on YouTube of an individual with a seemingly British accent apparently joining with militants in celebrating the "conquests in Iraq" by ISIS rebels.
ITV News has not yet been able to independently verify this video.
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."
