Months after the Suruç attack, Turkey's capital city, Ankara, was rocked by two simultaneous suicide attacks.
The Ankara attack was the deadliest in the history of the Turkish Republic as 102 people were killed in the incident. Two suicide bombers detonated themselves in a rally near the capital's main train station
According to security authorities, the Suruç attack was also carried out by the Daesh terrorist organization, while the Ankara attacks were conducted by a cooperation between Daesh and the PKK terrorist group.
