According to London, former Russian military intelligence (GRU) Colonel Sergei Skripal, 66, who had been convicted in Russia of spying for Great Britain and later swapped for Russian intelligence officers, and his daughter Yulia, 33, suffered the effects of an alleged nerve agent in the British city of Salisbury on March 4.
Both men match the appearance of the security camera footage released by British police in detailing their case against the men, although their hair color now appears lighter.
Boshirov and Petrov said they visited the southern English city of Salisbury in March, calling it a "wonderful town" and saying they wanted to see the famous Salisbury Cathedral.
'Today - just as we have seen throughout - they have responded with obfuscation and lies'. "Buy tickets to London right now, it's just an hour's trip away by train", the firm tweeted on Thursday, adding a link to their product.
The two Russian men, who say they are both about 40, were identified last week as suspects by the British government.
Margarita Simonyan, the editor-in-chief of Russia's state-funded RT, wrote on social media that she had met and interviewed two men called Petrov and Boshirov yesterday evening. "We got wet, took the nearest train and came back" to London, they told RT, Russia's state-run global broadcaster.
"From the very start we planned to go to London and, put bluntly, cut loose and have some fun", he said in the interview which was pre-recorded on Wednesday and broadcast on Thursday. "We'll see in the near future".
Russian Federation has repeatedly denied any involvement in the case.
Trump promises all-out response to Hurricane Florence
Hurricane Maria pummelled Puerto Rico in September 2017, wreaking widespread devastation and causing US$90 billion in damages. Hostin further bashed the Trump administration for not doing enough to stop preventable deaths after the storm.
The affair returned to the headlines in July when a woman near Salisbury, Dawn Sturgess, died and her partner Charlie Rowley fell ill after Rowley found a counterfeit bottle of Nina Ricci perfume containing the Novichok nerve agent and brought it home.
The men denied the allegations and said they visited Salisbury on March 3 for tourism but stayed for 30 minutes only. They said they had fallen victim to a "fantastical coincidence".
The men are civilians and "we know who they are", Putin told an economic forum in Vladivostok on Wednesday in his first comments on the United Kingdom allegations.
The pair, who the United Kingdom suspect of being members of Russia's GRU military intelligence agency, complained their lives had been "turned upside down" and RT said they sounded distressed during the interview.
Britain named Petrov and Boshirov as the two men suspected of poisoning Sergei Skirpal, 66, and his 33-year-old daughter, Yulia, and said the duo work for Russian military intelligence.
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. We know who they are, we have found them already. They recovered after treatment in the hospital.
Mr Boshirov said: "When your life is turned upside down, you don't know what to do and where to go". We went through the corridor together, we always [do it] together.
