The BBC has been lively commenting on the Bulgarian trace in the explosion of ammunition depots in the Czech Republic in 2014. The media reported that one of the people who stored in Vrbetica ammunitions that were meant for Ukraine was the Bulgarian arms dealer Emilian Gebrev, who six months after the explosion became the target of an assassination with an unknown nerve agent in Sofia.

The chief suspects behind the Salisbury poisonings and the organisers of an alleged coup in Montenegro in 2016 may have had close links, according to the British conservative Daily Telegraph newspaper, citing a Bellingcat investigation.

British Security Minister Ben Wallace said Thursday that Russian President Vladimir Putin had "ultimate" responsibility for a nerve agent attack on a former Russian double agent in England in March.
