Authorities confirmed 22 people dead in the capsizing of a tugboat with an international team on a test voyage in eastern China, after rescuers dragged the overturned vessel to shallow waters and scoured it Saturday. Four Singaporeans, an Indian, an Indonesian, a Japanese and a Malaysian were among the dead in the accident on the Yangtze River, and the 14 other victims were Chinese, the state-run Xinhua News Agency said. The newly built, 30-meter (98-foot) long Wanshenzhou 67 was on a test voyage Thursday in the river's Fubei Channel in Jiangsu province when it suddenly turned over. The ship's owner, parts suppliers and engineers were among the 25 people aboard for the test, AP reported.
