Turkey on Monday marked the seventh anniversary of the bloodiest terrorist attack in its history, but many of the Islamic State (IS) suspects charged over the bombing that killed 103 people in Ankara have yet to be brought to justice.
Sixteen suspects accused of organizing the attack and leading IS activities in Turkey remain on the run, as lawyers for the victims' families blame neglect of duty on the part of the authorities for the failure to hunt down the fugitives and prevent the attack in the first place.
