REUTERS/Vasily FedosenkoKYIV, Aug 4 (Reuters) - The Security Service of Ukraine accused Russia on Friday of preparing to stage a "false flag" attack at the Mozyr oil refinery in Belarus in order to blame Ukrainian saboteurs as part of an effort to draw Minsk into the war in Ukraine. Fighters from Wagner, a Russian mercenary group, launched a mutiny against the Russian defence establishment in June and some of its fighters have since moved to Belarus under a deal. There was no immediate comment on the Ukrainian statement from Russia or Belarus.
