British Prime Minister Theresa May has insisted that two suspects in the poisoning of a former Russian double agent and his daughter should be "brought to justice," before meeting Russian President Vladimir Putin in Japan.
Britain has accused two officers from Russia's military intelligence agency, the GRU, of being responsible for the poisoning of Sergei Skripal and his daughter Yulia with a nerve agent in the English city of Salisbury in March 2018.
May met Putin on the sidelines of a G20 summit in Osaka, Japan on Friday.
"Russia does not allow the extradition of its nationals, but European arrest warrants are out for those two individuals and if they set foot outside Russia we will be making every effort that they are brought to justice," she told the BBC before the meeting.
She urged Moscow to stop its "destabilising activities," including disinformation and cyber-attacks.
Putin rejected Britain's claims of Russian state involvement in the nerve agent poisoning, suggesting that both sides could be ready to put the incident behind them.
"I think Russia and UK are both interested in fully restoring our relations, at least I hope a few preliminary steps will be made," he told the Financial Times.
Putin added that spies who betray their country must be punished.
"I am not saying that the Salisbury incident is the way to do it ... but traitors must be punished," he said.
