On October 12, 2023, over 300 Estonian educational institutions also received similar letters. The threatening letters were signed by 'Andrey Glubokoslavsky,' who identified himself as a member of the Russian Razvedka and co-author of the terrorist group 'Pribaltiyskiy Vilayat.' The letters state several explosive devices were planted with a detonation time at 10:40 and threaten to kill everyone in the building. 'Pribaltiyskiy Vilayat' is a known terrorist group with a closed Telegram channel of about 2,867 subscribers. The warnings include violent and territorial claims against Estonia and Latvia, which constitutes psychological and physical threat to educational environments.",

Responsibility is claimed by the terrorist group 'Pribaltiyskiy Vilayat,' which is active on Telegram with a closed chat.
