>> These are the two men British authorities suspect of attempting to murder a former Russian spy and his daughter in a nerve agent attack on British soil. The British government says they're Russian agents, acting on orders from high up in the Russian state. And British police say they forensically pieced together the pair's movements, putting them in the same place at the same time that Sergei and Yulia Skripal were exposed to Novichok.
>> That based on a body of intelligence, the government has concluded that the two individuals named by the police and CPS are offices from the Russian military intelligence service
so known as the GRU.>> The men have been named as Alexander Petrov and Ruslan Boshirov though UK authorities say those are probably aliases.
By analyzing thousands of hours of CCTV footage British police have reconstructed their alleged movements in the days around the March the 4th incident. These images show the men arriving two days earlier. They checked into this hotel in London. Traces of Novichok were found in their room. CCTV footage also shows them in Salisbury on the day the Skripals were poisioned.
Then they flew back to Moscow that evening. The police theory is that a counterfeit bottle of Nina Ricci perfume was used to spray Novichok on the front door of Sergei Skripal's home. That bottle was later found by UK citizen, Charlie Rowley. He and his partner, Dawn Sturgess also fell ill, and Sturgess died in July.
May said Petrov and Boshirov are also the prime suspects in that case, but the UK is not seeking extradition, as Moscow does not extradite Russian nationals. A European arrest warrant has been issued. The incident sparked an East-West rift that saw the UK and other countries expel scores of Russian diplomats and the Kremlin responding in kind.
Russia has consistently denied any involvement and on Wednesday it said it does not recognize the names given by Britain.
