UK Launches Probe Into 14 Other Suspected Russian Assassinations

U.S. intelligence officials have reportedly advised British authorities as many as 14 U.K. deaths in recent years previously attributed to natural causes might in fact be assassinations linked to Russia.

The 14 suspicious deaths are in addition to the 2006 assassination of Putin rival Alexander Litvinenko, whose tea was laced with radioactive polonium-210 at the Millennium Hotel in London, and the March 4 attack on former Russian intelligence officer Sergei Skripal and his daughter Yulia.
