There was no claim of responsibility for the Oct. 10, 2015 attack that targeted a peace rally, but Turkish authorities blamed the attack on home-grown Islamic State militants.
Anadolu Agency said today the Ankara prosecutor's office has charged 36 people with crimes against the state, killing some 100 people, attempting to kill 391 people who were hurt in the attack and possession of arms and explosives.
Anadolu said they would collectively face more than 11,000 years in prison, but didn't provide a breakdown.
