Turkey is close to identifying one of the two suspects in Saturday's twin blasts in Ankara that killed at least 97 people, Prime Minister Ahmet Davutoglu said on Monday.
DNA tests are being carried out on the remains of the suicide bombers, Xinhua quoted Davutoglu as saying.
The attack was an attempt to influence the outcome of the snap election on November 1, Davutoglu said, adding necessary steps will be taken to further enhance security.
No group or individual has claimed responsibility for the attack which targeted a peace rally in Ankara.
