British Prime Minister David Cameron is to meet with security chiefs this week to decide what action, if any, should be taken against Russia following the publication of a report about the death of Alexander Litvinenko, set to be released on Thursday, British newspaper The Daily Mail reported.
A Downing Street aide told the paper the report would blame the Kremlin for the killing, but added 'we won't be declaring war on Russia', according to the report.
Intelligence sources told the paper there was no 'smoking gun' pointing to the Russian leadership, but there was 'no doubt' about the people who were physically responsible'.
