Syria's state media and an activist group say a twin bombing attack targeting Kurds celebrating their New Year has killed and wounded dozens of people.

State TV said the two bombings targeted Kurds in the northeastern city of Hassakeh. The Britain-based Syrian Observatory for Human Rights said Friday's attack killed and wounded as many as 100 people.

The Observatory said one of the attacks was carried out by a suicide bomber who belonged to the Islamic State group.

Kurdish fighters have been fighting the Islamic State group for months in battles that have left hundreds dead.

Hassakeh province is predominantly Kurdish but the Islamic State holds parts of the region that borders Turkey and Iraq.
