American warplanes are carrying out further airstrikes against Islamist extremists in northern Iraq - to help Iraqi forces retake a strategic dam near the city of Mosul.

The dam was captured by Islamic State fighters earlier this month.

They have been accused of a massacre of hundreds from the minority Yazidi sect.
