A US tour bus carrying 14 Chinese tourists has crashed on a highway near the Hoover Dam. Authorities say at least seven have been killed, and the other seven were seriously injured. 

Six fatalities were confirmed on the scene, about 64 kilometers northwest of Kingman, Arizona. A seventh person died at the University Medical Center in Las Vegas.

The Arizona Department of Public Safety says the bus was travelling north on UShighway 93 when it veered across the median. It rolled at least once before stopping. Tourists on the bus were Chinese nationals who had flown from Shanghai to San Francisco. Police say they are busy with the identification.

Commander Dean Nyhart of Arizona Dept. of Public Safety, said, "We don't have any fingerprints to help match it up to the people that we have here that are deceased at the scene, so it's going to be a lengthy investigation just to identify the deceased people and get the right passports back into the right hands right now. But we obviously have a language barrier from the few people that could actually talk to us initially at the scene, which was another tour bus full of Chinese nationals that stopped to help initially. They were able to provide some interpretation for us."
