Chuck Hagel: Iraq dam 'critically important facility'

The US has carried out a series of air strikes on Islamic State militants close to the vital Haditha dam in western Iraq, US officials say.

US Defence Secretary Chuck Hagel said the dam was critically important for Iraq, and American interests would be threatened if it fell.

He said the attacks had been carried out at the request of the Iraqi government.
