The death toll from the double suicide bombing in Ankara now stands at 99, Turkish Prime Minister Ahmet Davuto?lu said on Oct. 14, lightly raising the previous toll of 97 people.

The two suicide bombers who perpetrated Turkey's deadliest terrorist attack ever on Oct. 10 in Ankara have been identified, with one of them an Islamic State of Iraq and the Levant (ISIL) member whose brother killed 33 people on July 20 in Suruç in a separate bombing.

Prime Minister Ahmet Davuto?lu revealed on Oct. 12 that the government was considering the Islamic State of Iraq and the Levant (ISIL) as the ?first suspect? of the Ankara twin bombings on Oct. 10 which claimed at least 97 lives so far according to official figures with reports of a rising toll.

In the bombings, 10-kg cluster bombs were detonated. Authorities believe a hand grenade could have been used rather than a remote-controlled detonator.
