A strong earthquake killed more than 100 people in Tibet and left many others trapped in the autonomous region of western China, state media say.

Rescue workers in China ’s mountainous Tibet region are racing to reach survivors trapped under the rubble as night temperatures drop far below freezing point following a powerful earthquake.

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.
