Experts from the U.S. Federal Bureau of Investigation (FBI) who have been assisting in the investigation of the 3 February death of Zurab Zhvania told journalists in Tbilisi on 1 April that they found no evidence that Zhvania was killed deliberately, rather than succumbing to fumes from a faulty gas heater. But veteran politician Irina Sarishvili-Chanturia repeated on 1 April her conviction that Zhvania was murdered, Interfax reported. She accused the FBI and the Georgian authorities of conspiring to conceal the true cause of Zhvania\'s death. (Caucasus Press)
