A man who was arrested after a terrorist attack in Moscow suburbs died in a Moscow police station

“1ADAT” also published a video showing his corpse after an autopsy. In it, a person states that he was hanged by the security services.

It has already been reported that Russia detained four citizens of Tajikistan on suspicion of carrying out a terrorist attack and seven other persons who are suspected of being involved in planning the attack.

The “Islamic State” group claimed responsibility for the terrorist attack. Western security experts believe that the Afghan branch of this organization – the “Islamic State – Khorasan Province” group – is behind the attack.

Russian dictator Vladimir Putin has admitted that the attack was carried out by “radical Islamists”, but continues to insist, without any evidence, that Ukraine and the West were involved.

In the wake of the attack, Russian security services have been criticized for failing to prevent the attack, despite US intelligence agencies privately and publicly warning of extremist plans to attack places in Moscow where large crowds gather.

The “Reuters” news agency, citing anonymous sources, reported on Sunday that a few days before the Crocus City Hall attack, Iranian intelligence services informed their Russian colleagues about the information obtained during the interrogation of detained terrorists that a large-scale attack was being prepared in Russia.
