Seven people died and 10 were injured when the bus carrying 15 of a 20-member tour group crashed en route from Las Vegas to take a trip to the Hoover Dam in Arizona.

The Shanghai tourism bureau has asked the U.S.-based Galaxy Travel Agency to escort the five people who abstained from the trip to a Las Vegas hospital to identify the injured and the dead tourists.

Six Chinese tourists and a travel guide died and 10 others, including the driver, were injured when the bus crashed on a highway south of the Hoover Dam at about 3:04 p.m. local time Friday.

Six people died at the scene and one other died later at a Las Vegas hospital. Two of the injured have been discharged from the hospital.

Shanghai Mayor Han Zheng Saturday instructed the local tourism bureau to keep contacts with the travel group and ascertain more information.

The bureau is to set up a work team with the two tour organizers -- the Shanghai Donghu Travel Agency and Galaxy Travel Agency. Galaxy will send staff to the hospital, and establish contact with Chinese and U.S. insurance agents.

The Shanghai government is still waiting for further reports from the U.S. authorities.
