Beijing warned of second earthquake
China has deployed troops to help victims of a 7.8 magnitude earthquake that struck the southwest today, with at least four children killed and 100 injured when two schools collapsed. The earthquake was so strong it was felt as far west as Thailand's capital Bangkok, some 3300km away, where office buildings swayed for several minutes. It also swayed buildings in the Taiwanese capital of Taipei, and was felt in Hong Kong. China had sent military troops to help with disaster relief work, the state-run Xinhua news agency said.
