IS claims responsibility for triple north Syria suicide attacks that killed 26 people

The Islamic State 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 IS 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 IS and have captured dozens of villages and towns over the past year from the extremists, including Tal Tamr.

The Islamic State group has accused Somalia's al-Qaida affiliate of killing several jihadi leaders who defected to its side, including a Sudanese sentenced to death for killing a U.S. diplomat in Khartoum and his driver.

A detailed report posted on two IS-affiliated websites on Friday said al-Shabab leaders ordered the killing and detention of dozens of jihadis who expressed their willingness to join IS. They include Mohamed Makawi, a Sudanese who took part in the drive-by shooting of John Ganville and his driver in Khartoum on Jan. 1, 2008.

Makawi and another accomplice, Abdelbasit Haj Hamad, were among four sentenced to death in Sudan for killing Granville but escaped from prison in 2010.

The U.S. offered up to $10 million for information leading to the capture of the two men.
