Turkey puts 36 Islamic State suspects on trial over 2015 Ankara bombing

Turkey on Monday put 36 suspects on trial over a double suicide bombing last year blamed on Islamic State militants that killed over 100 people in the country's deadliest attack.

The bombing on 10 October, 2015 outside Ankara's main train station targeted mainly young people attending a peace rally of pro-Kurdish and leftist activists that was to start later that day.

Supporters of the victims have until now bitterly criticised the slowness of the investigation into the attack, which further raised tensions between the authorities and the Kurdish minority. The trial got underway at the Ankara criminal court in the presence of opposition MPs and families of the victims, several of whom shouted "murderers" at the suspects, reports said.

Thirty-five of the suspects are Turkish while one - named as Valentina Slobodjanjuk - is a Kazakh citizen, the state-run Anadolu news agency said.

Several of the suspects face multiple sentences of up to 11,750 years in prison each on charges of murder and seeking to change the constitutional order. Others face lesser charges of being a member of IS and face up to 22.5 years in prison, Anadolu said.

The hearing was taking place under the highest security, with security forces in body armour and helmets standing guard inside the courtroom, images showed.

The authorities have identified one of the suicide bombers as Turkish citizen Yunus Emre Alagoz. The other was a Syrian citizen who has yet to be identified, Anadolu said.

Turkey has in the last year been hit by a string of major suicide bombings blamed on IS including a triple attack at Istanbul's main airport in June that left 47 dead and an August blast at a Kurdish wedding in the southeastern city of Gaziantep that killed 57 people, 34 of them children.

IS, which is believed to operate sleeper cells in major Turkish cities, never claimed these attacks.

A news agency affiliated to IS said they staged a bombing on the southeastern city of Diyarbakir last week that killed 11.

If confirmed, it would be the first claim by IS for an attack in Turkey. But on Sunday, the Kurdistan Freedom Falcons (TAK), seen as a splinter group of the better-known Kurdistan Workers Party (PKK), said it had carried out the attack.
