Bellingcat last year identified two of the main suspects in the attack. The UK, Germany, the United States and France have said there is "no plausible alternative" to Moscow's involvement, demanding the Kremlin provide information about its nerve agent reserves.
What Bellingcat said:
- "Bellingcat can now reveal the true identity and background of this GRU officer, who operated internationally under the cover persona of Sergey Vyachaeslavovich Fedotov"
- "In fact, this person is Denis Vyacheslavovich Sergeev, a high-ranking GRU officer and a graduate of Russia's Military Diplomatic Academy"
- "In the last two months, Russian authorities have taken the unusual measure of erasing any public records of the existence of Denis Sergeev"
- "These unprecedented actions cannot plausibly be taken without direct involvement of the Russian state"
'Our local boy'Last year, Bellingcat made headlines when it identified the two main suspects in the Skripal poisoning, Anatoly Chepiga and Alexander Mishkin. In one case, a partner Russian news site, The Insider, sent a reporter to the home village of one of the Russian operatives.
"The reporter was able to meet and talk to many residents, who all recognized 'Alexander Petrov,' the person shown on photographs released by the British police and seen in the RT interview, as 'our local boy' Alexander Mishkin," Bellingcat wrote at the time.
Bellingcat said Sergeev may have also been involved in the poisoning of a local arms dealer in Bulgaria. British police have refused to confirm whether they were investigating a third suspect in the Skripal poisoning.

Amateurish operationsIn October, Ben De Jong, an expert on Russian intelligence activities at the University of Amsterdam, told DW that the latest bungles were a blow to the GRU, Russia's military intelligence.
"It's definitely a step back for the GRU and also for other Russian services," De Jong said. "Not only because all these names have become known, but also because they have been shown to be almost amateurish in many ways; in the way they carried out their operations."
