More than 200 China relief workers buried by mud

BEIJING (Reuters) - More than 200 relief workers in quake-hit southwestern China have been buried by mudflows over the past two days, the Transport Ministry reported on Monday.

Details of the accidents were not immediately available. It was unclear whether any of those buried had been pulled out alive.

News of the mudflows came seven days after a 7.9 magnitude quake hit Sichuan province, killing more than 30,000 people. Hundreds of aftershocks have since rattled the vast mountainous region.

There have been numerous rockslides from unstable mountain slopes, and blocked rivers swollen by heavy rain have threatened to burst their banks.
