In this file grab taken from CCTV and issued by the Metropolitan Police in London on September 5, 2018, Ruslan Boshirov and Alexander Petrov walk on Fisherton Road, Salisbury, England, March 4, 2018.
President Vladimir Putin's spokesman, Dmitry Peskov, said Friday that Russian authorities will consider Britain's request to interrogate them if it comes.
"The government is clear these men are officers of the Russian military intelligence service - the GRU - who used a devastatingly toxic, illegal chemical weapon on the streets of our country".
"We have repeatedly asked Russian Federation to account for what happened in Salisbury in March and they have replied with obfuscation and lies".
Alexander Petrov and Ruslan Boshirov gave an interview today to RT, a Kremlin-financed media outlet that works as a propaganda outlet for the Russian government.
Boshirov acknowledged they may have been near Mr Skripal's house but they did not know where it was. They said they had fallen victim to a "fantastical fatal coincidence". "What is our fault?"
The Kremlin assassins who attempted to poison Sergei and Yulia Skripal with the Novichok nerve agent allegedly enjoyed a drug-fuelled night with a prostitute just hours before the Salisbury attack.
A televised interview with citizens of Russia Ruslan Bashirov and Alexander Petrov, suspected of poisoning ex-GRU officer Sergei Skripal, was a punishment for them for the failure of the British operation in Salisbury.
Borishov claimed a friend had been "suggesting for a long time that we visit this wonderful town".
British Prime Minister Theresa May last week said the attack was "almost certainly" approved "at a senior level of the Russian state".
"They explained everything simply and clearly yesterday, why they went there, what they were doing there, what the weather was like", he said.
British police claim the names used by the men are aliases and there is evidence they are Russian military intelligence agents.
According to The Daily Mail, on the eve of the assassination of Bashirov and Petrov brought into the room of the prostitute. He laughed off as "silly" the idea that they would have carried a women's perfume bottle.
She said: "Unfortunately we have had quite a history of foreign leaders and foreign secret services lying to the world".
"They are wanted men and we have taken all steps to ensure they are apprehended and brought to justice in the United Kingdom if they ever again step foot outside Russian Federation". "I hope they will come forward and tell about themselves".
Britain released CCTV footage and photographs showing the two men walking in Skripal's neighbourhood.
Russian Federation has denied the two men were military intelligence agents. "But when we came there, even a plane...we thought it will not be landed on the first try, as the transport collapse took place in England on March 2,3, the snowstorm", Petrov said.
The failed attack triggered a major diplomatic crisis between the United Kingdom and Russian Federation, with the British government alleging Moscow was responsible for the attempted murder.
