Eliot Higgins, founder of the investigative platform Bellingcat, delved into the open source evidence. His team identified links with Russia's 53rd Anti Aircraft Missile Brigade, and trawled through 200 soldiers' social media posts to confirm the identity and role of many members of the unit based at a Russian military barracks in Kursk. Bellingcat shared their findings with Dutch prosecutors. He believes the trial has laid bare indisputable proof of Russia's involvement.
