Turkey's prime minister says authorities are close to identifying one of the suicide bombers who carried out the blasts in Ankara that killed 97 people.

Ahmet Davutoglu said evidence point to "a certain group" which refused to identify in a group interview on Monday. However, he confirmed that the Islamic State group was the "No.1 priority" of the investigation.

Davutoglu said the attacks that targeted activists gathering for a rally to call for peace with the Kurdish rebels were aimed to "cast a shadow" over Turkey's Nov. 1 election and to influence the result. He did not elaborate.

The Turkish leader rejected accusations that Turkey was being drawn into the crisis in Syria saying: "These attacks won't turn Turkey into a Syria."
