China on Monday begins a three-day national mourning for the tens of thousands of people killed in a powerful earthquake which struck the country's southwest on May 12.

At 4:58 a.m., the national flag at the Tian'anmen Square in downtown Beijing flew at half-mast after a complete flag-raising ceremony.

All national flags will fly at half-mast at home and at Chinese diplomatic missions abroad from Monday to Wednesday. Public recreational activities will be halted during the mourning period.

At 2:28 p.m. Monday, Chinese citizens nationwide will stand in silence for three minutes to mourn for the victims, while air raid sirens and horns of automobiles, trains and ships will wail in grief.

In the mourning period, condolence books will be opened in China's Foreign Ministry and Chinese embassies and consulates around the world.

The Beijing Olympic torch relay will also be suspended from Monday to Wednesday.

The death toll from the massive quake rose to 32,476 nationwide as of 2 p.m. Sunday, while the injured numbered 220,109, according to the emergency response office under the State Council.

Among the dead, 31,978 were in Sichuan alone with the rest in six other provinces and a municipality.

The quake hit Wenchuan County, Sichuan Province, at 2:28 p.m. of May 12. Many other areas were also affected.

The search, rescue and disaster relief efforts are continuing. Some 113,080 Chinese soldiers and armed police have been mobilized to help with rescue operations. Rescue teams from Russia, the Republic of Korea, Japan and Singapore, as well as Taiwan and Hong Kong regions, have also joined in relief efforts.

Rescuers carry Shen Peiyun, who is saved 145.5 hours after Monday's earthquake, to a hospital at Yingxiu Township of Wenchuan County, the epicenter of Monday's earthquake in southwest China's Sichuan Province, on May 18, 2008.
