Aid drop follows US raids in Iraq

The US has conducted its second air-drop of food and water to thousands of Iraqis hiding in mountains from jihadist fighters, the Pentagon says.

The move came hours after the US launched fresh air strikes against militants from the Islamic State (IS).

The group had recently made fresh gains in northern Iraq and is threatening the Kurdish city of Irbil.
