DAMASCUS, Syria - The Islamic State group has claimed responsibility for a bomb blast that killed at least five people in the northeastern Syrian city of Hasakeh.

The extremist group's Aamaq media agency posted that this morning's suicide attack killed and wounded 15 people.

Syrian state media said the attacker blew himself up on his motorcycle at a traffic circle.

The Syrian Observatory for Human Rights monitoring group said three Kurdish Syrian police officers were killed in the blast.

At least 38 people were killed in a string of bomb blasts in government-controlled territories. The attacks were timed closely together, though the Islamic State group did not claim responsibility for the attacks in Homs, Tartus, and the Damascus suburb of Saboura.
