As speculation mounts in Britain over the Kremlin's alleged role in the attempted murder of former Russian double agent Sergei Skripal and his daughter Yulia, Russian state television has aired an interview with President Vladimir Putin on tensions between Moscow and the West
"Those who serve us with poison will eventually swallow it and poison themselves," said Putin. His comments were not made in reference to the Skripal case in which Russia denies any involvement.
Nonetheless, some UK lawmakers, however, are urging police to reopen inquiries into recent deaths of Russian exiles in Britain.
Scientific tests by government experts have identified the specific nerve agent used, which will help identify the source, but authorities have refused to disclose the details.
Meanwhile, UK police are continuing to comb the scene in Salisbury where Skripal and his daughter were poisoned by a nerve agent. The Skripal's remain critically ill in hospital. But an officer initially called to assist the pair has regained consciousness after being exposed to the highly toxic substance.
"This was a very serious incident, which is why we've got the police down there in full force conducting the investigation, which is why we're giving all the support we can, the medical support necessary, to the people who've been affected," said Amber Rudd, Britain's interior minister.
