The China International Search and Rescue Team (CISAR), one of the main rescue groups sent to northwest China's Yushu prefecture after the April 14 earthquake, returned to Beijing Monday after finishing their work in the quake zone.

The rescue workers of the team were from the General Hospital of the Armed Police Forces, the China Earthquake Administration and a sapper corps in Beijing.

Equipped with two rescue vehicles, nine sniffer dogs and two tonnes of rescue equipment and medicine, the CISAR searched 208 sites and saved seven survivors who were buried in the debris.

It also helped carry more than 100 tonnes of relief materials, and treat 1,507 injured people in 12 days. It donated 4 million yuan (585,811 U.S. dollars) in medical equipment and medicines in value.

Established in 2001, the 230-strong CISAR previously helped in rescue work after the 2008 Sichuan earthquake, this year's Haiti earthquake and the 2004 Indian Ocean tsunami.
