The hostage crisis led to a debate about how militants managed to enter what currently is the largest courthouse in Europe with guns and flags without being stopped , as well as whether the incident and the massive power outage were related . Amid speculation that the government would use the incident to their own political gain , former Deputy Prime Minister Emrullah İşler claimed in a tweet that the militants were from the same organisation as the Gezi Park protesters in 2013 . CHP leader Kemal Kılıçdaroğlu later publicly criticised the government for trying to associate his party with the terrorists . The mother of Şafak Yayla , one of the militants , accused the government of hiding the real perpetrators behind the hostage crisis and killing her son instead . A similar situation had occurred in January , where DHKP-C claimed responsibility for a suicide bombing , before removing this claim from their website when the perpetrator was later linked to ISIS instead
