Estonia’s Internal Security Service has confirmed that Russia’s military intelligence agency, the GRU, ordered an arson attack on the Estonian defence industry company Threod Systems on 14 November. The attempt was unsuccessful.
This was reported by Estonia’s Foreign Minister Margus Tsahkna.
At 03:06 on 14 November, an attempt was made to attack the premises of the defence company Threod Systems, which manufactures drones, with the aim of causing an explosion and setting the building on fire.
According to the minister, the suspects have been detained and criminal proceedings have been opened.
“This is yet another example of how Russia uses sabotage and coercion to destabilise our societies, sow fear and divert attention from supporting Ukraine,” his post on the social platform X says.
Tsahkna stressed that Tallinn will continue to work closely with international partners to identify, expose and hold accountable anyone who seeks to threaten our security or stability. “At the same time, we will continue to increase pressure on Russia through sanctions, isolation and entry restrictions—until it ends its aggression against Ukraine and takes full responsibility for its actions,” the official said.
At 3:06 a.m. on November 14, an attempt was made to attack the premises of a defense industry company Threod Systems that manufactures drones, with the aim of causing an explosion and setting the building on fire. We have quickly detained the suspects. We advise against even considering such job offers from Russia. The consequences are serious!
