LONDON - Britain's attempts to get an explanation from Russia over the poisoning of a former Russian spy in Salisbury have been met with obfuscation and lies and that hasn't changed, Prime Minister Theresa May's spokesman said on Wednesday.Russian President Vladimir Putin said Russia knew the real identity of the two men accused by British prosecutors of trying to murder Sergei Skripal and his daughter Yulia. According to Putin's statement, they were civilians with nothing criminal about them."These men are officers of the Russian military intelligence service, the GRU ... The government has exposed the role of the GRU, its operatives and its methods, this position is supported by our international allies," the spokesman told reporters."We have repeatedly asked Russia to account for what happened in Salisbury in March and they have replied with obfuscation and lies. I can see nothing to suggest that has changed."
