Breaking: US carries out four more military strikes against ISIS

The US military says it has carried out four new air strikes on militants to defend civilians in northern Iraq.  US Central Command said jet fighters and drones had destroyed armoured carriers and a truck that were firing on civilians. Thousands of civilians fled into mountains after the Islamic State (IS) overran the town of Sinjar a week ago.

This is the third round of US air strikes since they were authorised by President Barack Obama.
