At least 29 people were killed and 166 wounded in the two explosions outside an Istanbul soccer stadium on Saturday night.

The two explosions were caused by a car bomb which was followed by a suicide bombing less than a minute later.

Turkish Interior Minister Suleyman Soylu said that all but two of those killed in the blasts were police officers, according to Reuters. He said 17 of the wounded were undergoing surgery and another six were in intensive care.

Deputy Prime Minister Numan Kurtulmus said the suicide bomber had detonated 45 seconds after the car bomb. Soylu said 10 people had been detained based on evidence from the detonated vehicle.

Earlier, Turkish President Recep Tayyip Erdogan issued a statement in which he confirmed the explosions were a terrorist attack which targeted police and civilians and aimed to cause as many casualties as possible.

"A terrorist attack has been carried out against our security forces and our citizens. It has been understood that the explosions after the Besiktas-Bursaspor soccer game aimed to maximize casualties. As a result of these attacks unfortunately we have martyrs and wounded," he said, according to Reuters.

According to reports, the first and larger explosion took place about 10:30 p.m. after the home team Besiktas beat visitor Bursaspor 2-1 in the Turkish Super League.

Turkish Transport Minister Ahmet Arslan called the attack an act of terrorism on Twitter, Reuters reported.
