A Reuters reporter saw at least 20 bodies covered by flags and banners, including those of the pro-Kurdish opposition Peoples' Democratic Party (HDP), with bloodstains and body parts scattered on the road.

Authorities were investigating claims the attacks were carried out by a suicide bomber, two government officials told Reuters. Prime Minister Ahmet Davutoglu was due to hold an emergency meeting with the heads of the police and intelligence agencies and other senior officials, his office said.
