People mourn during the funeral of Timur Miller, a resident of Ulyanovsk and one of the victims of the plane crash in Egypt who died at the age of 33, at a cemetery in St. Petersburg, Russia, November 6, 2015. With world powers divided over the cause of a Russian jetliner crash, much rests on forensic teams as they scour a sandy trail of wreckage almost a week after 224 people died in Egypt's worst air disaster.
