Sunni insurgents led by Islamist group Isis have captured three towns in Iraq's western Anbar province, witnesses and security sources told Reuters.
"Army troops withdrew from Rawa, Ana and Rutba this morning and Isis moved quickly to completely control these towns," a military intelligence official said.
The office for the prime minister's military command said it had no immediate comment and would be giving an update on events in a press conference later on Sunday.
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."
