Kurds are an ethnic group who live in a sizeable area, though not a national one that borders Turkey, Syria, Iraq and Iran. It is referred to as Kurdistan
As this is being written there is a battle going on between the Kurds in a Syrian town on the border with Turkey, Kobani, and the Islamic State (ISIS) militants that have seized a large area of northern Syria and Iraq. ISIS is also moving south toward Baghdad. The only area they have not been able to seize has been Iraq’s Kurdish region which has been virtually autonomous from what is left of the Iraqi government.
