A car bomb explosion ripped through a busy square in the Turkish capital Sunday evening, killing at least 34 people and wounding 125 others, officials said.

The death toll could include one or two attackers, Health Minister Mehmet Muezzinoglu said.

Scores of police cars, firefighters and medical personnel rushed to the scene. Security forces evacuated the area, the official Turkish news agency Anadolu reported.

“We condemn this terror attack. … People who carried out this attack will never succeed,” Interior Minister Efkan Ala said. “Turkey will overcome. Our determination to fight against terror will never be deterred by attacks like this.”

President Recep Tayyip Erdogan blamed regional instability for the violence.

“When terror organizations and the ones who use them as a tool start losing their fight against the security forces,” he said, “they apply the most cruel methods and target our innocent people.”

Authorities haven’t released details about who they believe was behind the blast.
