Russian intelligence was behind a chemical attack on Dmitry Muratov, the Nobel peace prize-winning editor of the Russian independent newspaper Novaya Gazeta, US officials have said.
Muratov has previously said he boarded a train on 18 April heading from Moscow to the city of Samara when he was splashed with red paint containing acetone by an attacker who told him: “Muratov, this is for you from our boys.”
