Two men among five new names on a U.S. sanctions list against Russia are the suspects believed to have carried out the London polonium poisoning of Kremlin foe Alexander Litvinenko in 2006. Andrei Lugovoi and Dmitry Kovtun are just two of the 44 Russians that President Obama has ordered censured before he leaves the White House in 10 days. Litvinenko died of radiation poisoning. A U.K. inquiry determined that Litvinenko, a former Russian spy, was most likely killed at the personal order of President Vladimir Putin. The people named in the U.S. sanctions are banned from traveling to the States and have had any assets within the country frozen.
