British police have issued arrest warrants for two Russian men over the nerve-agent poisoning of ex-spy Sergei Skripal and his daughter Yulia in the English city of Salisbury.
Sergei Skripal, a former colonel in Russia’s GRU military intelligence service, and his 33-year-old daughter, Yulia, were found slumped unconscious on a bench in Salisbury in March after a liquid form of the Novichok type of nerve agent was applied to his home’s front door.

However the pair survived the poisoning.
British Crown prosecutor Sue Hemming said on Wednesday the UK was not asking Moscow to extradite the men because Russian law forbids extradition of its citizens.
Police say the men, both about 40, flew from Moscow to London on Russian passports two days before the Skripals were poisoned on March 4.
Assistant Police Commissioner Neil Basu said the men were probably using aliases.
He appealed to the public “to come forward and tell us who they are”.
Police released a series of images of the men as they travelled through London and Salisbury between March 2 and March 4.
Police say the two men flew back to Moscow from Heathrow Airport on the evening of March 4, hours after the Skripals were found collapsed on a park bench.
Britain has issued a European arrest warrant for the suspects, meaning they can be detained if they leave Russia for another European country, but Mr Basu conceded it was “very very unlikely” police would be in a position to arrest them anytime soon.
British officials have blamed the Russian Government for the poisoning, a charge Moscow has denied.
