The explosion occurred during evening rush hour in the heart of Ankara, in an area close to parliament and armed forces headquarters and lodgings. Buses carrying military personnel were targeted while waiting at traffic lights at an intersection, the Turkish military said while condemning the "contemptible and dastardly" attack.
"We believe that those who lost their lives included our military brothers as well as civilians," Deputy Prime Minister Numan Kurtulmus said.
At least two military vehicles caught fire and dozens of ambulances were sent to the scene. Dark smoke could be seen billowing from a distance.
