Investigation Into Cause of Russian Plane Crash in Egypt

Russian officials, including President Vladimir Putin, say everything will be done to determine the cause of Saturday's plane crash in Egypt that killed all 224 people on board, most of them Russian tourists returning to St. Petersburg from an Egyptian Red Sea resort. More than half of the bodies have been found at the crash site on the Sinai Peninsula, and Egyptian authorities have expanded the search area in an effort to find others. VOA's Zlatica Hoke reports.
