BEIJING, Oct. 3 (Xinhua) -- There have been no reports so far of Chinese citizens injured or dead in the Las Vegas mass shooting, according to China National Tourism Administration (CNTA) on Tuesday.

Six Chinese tourists trapped in the blocked areas have all left safely, the administration said.

At least 59 people were killed and over 500 others wounded after a gunman opened fire on an open air concert Sunday night outside the Mandalay Bay Hotel in Las Vegas in the U.S. state of Nevada.

The massacre is believed to be the worst mass shooting in the U.S. history.
