Iraq has formally called on the United States to launch air strikes against jihadist militants who have seized several key cities.

"We have a request from the Iraqi government for air power," confirmed top US military commander General Martin Dempsey.

He told a Senate panel that it was in America's "national interest to counter [ISIS] wherever we find them".

The announcement came after insurgents launched an attack on Iraq's biggest oil refinery north of Baghdad.
