Iraq's biggest oil refinery, Baiji, has been shut down and its foreign staff evacuated, refinery officials said on Tuesday, adding that local staff remain in place and the military is still in control of the facility.
Militant group Isis have now apparently surrounded the refinery which shut down overnight, the sources said.
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."
