Sergei Skripal, a former double agent who was sent west in a 2010 spy swap, and his daughter, Yulia, were found unconscious on a bench in the English city of Salisbury that afternoon. Sturgess later died, but no one has been charged in that case.
Prime Minister Theresa May was adamant that this attack was not carried out by "rogue" GRU operatives. May said. "It was nearly certainly also approved outside the GRU at a senior level of the Russian state".
In July, an unnamed source told The Press Association that investigators had "identified the suspected perpetrators of the Novichok attack through CCTV and have cross-checked this with records of people who entered the country around that time".
The Skripal case has increased tension between the West and Russian Federation, and led to a flurry of sanctions and diplomatic expulsions.
"They must rein in the activities of the GRU".
Speaking ahead of the United Kingdom announcement, Kremlin spokesman Dmitry Peskov again denied any Russian role in the poisoning, saying that Russia has no new information about it because Britain has refused to share case files. Zakharova also said Moscow had asked the British embassy to let it examine fingerprint records that Russian nationals have to provide to obtain a British visa. "A link is being made with Russian Federation".
"We said right away that Russia had nothing to do with the Salisbury incident", Aleksandr Shulgin told Russian state media.
It's unclear how much further Britain or other countries will go in punishing Russian Federation for the poisoning. Ms. On Saturday they went to Salisbury, where Skripal had been living since being released in a prisoner swap between Britain and Russian Federation in 2010.
Prosecutors said the pair are in Russian Federation and can not be extradited. And Ms. May didn't call for further diplomatic expulsions.
Nadal to face Thiem in US Open quarters
However, Basilashvili could not maintain this level in the fourth set as Nadal broke for a 4-3 lead which he would not relinquish. A matchup with Thiem would be a rematch of the French Open final, won by Nadal, and their first not on clay.
The U.S. levied sanctions against Russian Federation at the end of August in retaliation for the attack.
Police are also still gathering information about the poisonings. He described an investigation which involved 250 detectives and analysis of some 11,000 hours of video.
Prosecutors from the service believe they have enough evidence to charge both Russians with conspiracy to murder Sergei Skripal, attempted murder of Sergei Skripal, Yulia Skripal and Nick Bailey, use and possession of Novichok contrary to the Chemical Weapons Act, and causing grievous bodily harm with intent to Yulia Skripal and Nick Bailey.
Police released a series of CCTV images they say show the two men, believed to be aged about 40, arriving at London Gatwick Airport on March 2 and in Salisbury on March 3 and 4.
CBS News correspondent Jonathan Vigliotti reports the police also released surveillance video on Thursday showing the two suspects near the site of the Salisbury poisoning in March.
Mr Basu said Novichok contamination was found in the London hotel where the two men stayed.
Officials determined that the same substance, found in a perfume bottle in a park weeks later, sickened a man and his girlfriend, who later died. Both the box and the bottle were labelled with the Nina Ricci brand.
Having taken advice from Public Health England, police say they are confident that there was no risk to members of the public who were on the same flight, trains or public transport used by the suspects.
"We do not believe Dawn and Charlie were deliberately targeted, but became victims as a result of the recklessness in which such a toxic nerve agent was disposed of", said Neil Basu, head of Counter Terrorism Policing.
