The US has launched an air strike against militants from the Islamic State (IS) group in Iraq.
The strike comes after IS, formerly known as Isis, took control of large areas of Iraq and Syria, driving minority groups from their homes.
US Secretary of State John Kerry described the IS "campaign of terror" as a wake-up call: "Its grotesque targeted acts of violence show all the warning signs of genocide".
