US launches more air strikes on IS militants in Iraq

US fighter jets and drones have launched a new series of air strikes targeting the Islamic State militants in northern Iraq.

The militants have been terrorising the Yazidi people in the north of the country, who are stranded on Mount Sinjar after coming under attack from IS.

The US also dropped food and water to the refugees on the mountain.
