An explosion killed at least 27 people and wounded 75 others on Sunday in the Turkish capital of Ankara, according to the Associated Press, which cited the Ankara governor’s office.

The blast originated from an “explosive-laden vehicle,” according to the Ankara governor’s office, and Turkish broadcaster TRT reported a car exploded near a bus stop.

Prime Minister Ahmet Davutoglu was convening an emergency security meeting.

A Turkish security official told Reuters that a Kurdish militant group likely carried out the attack.
