The Islamic State of Iraq and Syria (ISIS) group has claimed responsibility for triple suicide bombings in northern Syria that killed at least 26 people.

The group said in a statement posted online that the attacks in the predominantly Kurdish province of Hassakeh targeted offices of the main Kurdish militia known as YPG.

The attacks in the predominantly Christian town of Tal Tamr occurred late Thursday.

Syrian State TV and ISIS said on Friday the blasts killed 60 people while the Britain-based Syrian Observatory for Human Rights said they killed 26, including four Assyrian Christians.

Dozens of people were also wounded in the blasts.

The YPG has been one of the best forces in fighting ISIS and have captured dozens of villages and towns over the past year from the extremists, including Tal Tamr.
