Russian Foreign Minister Spokesperson Maria Zakharova pointed out that the saga of the alleged Novichok nerve agent should have come to a logical end, during a press-conference in Moscow on Thursday. «For four months we haven't heard anything from London except for unnamed sources and that it's «highly likely». Don't you think that there is a limit after which you should move to a more concrete... Еще, joint work?» she asked. Zakharova said that Moscow had repeatedly forwarded invitations to work in cooperation with London but had received no response, adding that the UK should put aside political «intrigues» concerning the investigation into poisoning. The comments come amidst developments of a «major incident» in the UK's town of Amesbury. A couple identified as Charlie Rowley and Dawn Sturgess — were taken to Salisbury hospital, after being found unconscious and in a critical condition at an address on Muggleton Road in Amesbury last Saturday. According to the police, it was due to exposure to the nerve agent Novichok. The same agent was supposedly used on former Russian spy Sergei Skripal and his daughter Yulia in Salisbury this March.
