Beijing - Twenty-one people are feared dead after a cave-in at a tunnel under construction for a subway line in the eastern Chinese city of Hangzhou, state media said on Sunday.
Rescuers had recovered three bodies by Sunday morning and held little hope of finding 18 missing construction workers alive, the official Xinhua news agency said.
"There is a slim chance for the survival of trapped workers, because of heavy flooding in the crater," the agency quoted Wang Guangrong, a spokesman for the rescue services, as saying.
The water in the hole left by the cave-in had fallen to about 3 metres after reaching 6 metres on Saturday, Wang said.
