Rescuers in China’s Tibet region searched Wednesday for survivors trapped in rubble, a day after a powerful earthquake killed at least 126 people and injured 188 others. Chinese officials said more than 400 people have been rescued so far. Some 30,000 people have also been relocated after the quake, which destroyed more than 3,600 homes.

Authorities moved more than 45,000 people in earthquake-hit Tibet to shelters in a massive rescue operation at the foot of the Himalayas as they wound down the search in a high-altitude environment where the odds of survival were always slim.

China has almost doubled its tally of injured in Tibet's deadly earthquake as rescuers widened a search on Friday for survivors in a remote county near the foothills of the Himalayas, despite dwindling hopes for survival.
