LONDON: British police said on Tuesday a third Russian had been charged in absentia with the 2018 Novichok murder attempt on former double agent Sergei Skripal, saying they could also now confirm the three suspects were military intelligence operatives.

The attack on Skripal, who sold Russian secrets to Britain, caused one of the biggest rows between Russia and the West since the Cold War, leading to the tit-for-tat expulsion of dozens of diplomats after Britain pointed the finger of blame at Moscow. Russia has rejected any involvement, casting the accusations as anti-Russian propaganda.

Skripal and his daughter Yulia were found unconscious, slumped on a public bench in the southern English city of Salisbury in March 2018. They and a police officer who went to his house were left critically ill in hospital from exposure to the military-grade nerve agent.

A woman later also died from Novichok poisoning after her partner found a counterfeit perfume bottle which police believe had been used to smuggle the poison into the country.

In September 2018, British prosecutors charged two Russians, then identified by the aliases Alexander Petrov and Ruslan Boshirov, with conspiracy to murder Skripal and the attempted murder of Yulia and the officer, Nick Bailey.
