Awwal 21, 1432, April 25, 2011, SPA -- Soldiers prodded marshy ground with slender poles and cleared mounds of rubble by hand Monday as 25,000 troops mounted Japan's largest search yet for the bodies of nearly 12,000 people missing in last month's earthquake and tsunami. The operation was the third intensive military search since the March 11 disaster, which splintered buildings, flattened towns and killed up to 26,000 people along Japan's northeastern coast. With waters receding, officials hope the team, which also includes police, coast guard and U.S. troops, will make significant progress during the two-day operation, according to a report of the Associated Press.
