Syria's Kurds face a new front in the war
After three years of conflict in Syria, a new front in the war has emerged.
The Kurds in the north of the country, who make up a tenth of the population, are not fighting the regime, but Islamic militants with links to al-Qaeda and the Islamic State in Iraq and Syria (ISIS).
Jim Muir has been to Syria to see this latest war within the Syrian war.
