BEIJING — The collapse of an under-construction railway bridge over a major river in China has killed at least 12 workers and left four others missing, state media reports said.

Aerial photos from the official Xinhua News Agency show a large section missing from the bridge's curved aquamarine arch. A bent section of the bridge deck hangs downward into the Yellow River below.

Sixteen workers were on the bridge in northwest China's Qinghai province when a steel cable snapped about 3 a.m. Friday during a tensioning operation, Xinhua said. Boats, a helicopter and robots were being used in the search for the missing., This news data comes from:http://evm-tc-nkmi-rr.gangzhifhm.com
