The first bodies of Russian victims killed in a plane crash in Egypt were transfered to St. Petersburg via a cargo plane on Monday. The Metrojet Airbus A321-200 crashed Saturday in the Sinai Peninsula and broke apart in mid-air, the Daily Beast first reported. Russian officials confirmed the plane broke up at high altitude and scattered bodies and debris over a large area, killing all 224 peple on board. A second Russian cargo plane is expected to fly more of the victims from Cairo to St. Petersburg late Monday, according to Emergency Situations Minister Vladimir Puchkov. President Vladimir Putin declared a national day of mourning while St. Petersburg, where many of the victims are from, is holding three days of mourning through Tuesday. More than 100 emergency workers have been sent the Sinai Peninsula to search for bodies and examine debris.
