This could be one of the major turning points of the war, and could be one of the major developments in current affairs world wide depending on how it goes. It really does look like the US have left a masisve power vacuum in Iraq.
The Iraqi army says it has driven off Islamist-led militants attacking the country's biggest oil refinery amid reports that most of it is in militant hands.





The army said 40 attackers had been killed, a claim which could not be verified independently.

Government forces have renewed air strikes on militants elsewhere.

Fighting is also reported in the western city of Ramadi.

The government is battling to push back ISIS (Islamic State in Iraq and the Levant) and its Sunni Muslim allies in Diyala and Salahuddin provinces, after the militants overran the second city, Mosul, last week.

Prime Minister Nouri al-Maliki has gone on television to tell Iraqis that gains by ISIS are a "setback" but Iraq has recovered its "national unity". He has long been accused of favouring the country's Shia Muslim majority.
