China boosts troops in rescue bid

China has stepped up its rescue operation, mobilising 30,000 extra troops and 90 helicopters, in the race to find survivors from Monday's devastating earthquake in Sichuan province. Nearly 15,000 people have been killed while another 26,000 remain buried in the rubble. But there are rare moments of hope: yesterday in Dujiangyan a woman eight months pregnant was pulled to safety after spending 50 hours trapped in rubble.
