China says 2 pilots killed in crash of navy jet China's navy says a fighter jet crashed during a training mission in the southern island province of Hainan, killing both pilots

BEIJING -- A Chinese navy fighter jet crashed during a training mission Tuesday in the southern island province of Hainan, killing both pilots, the navy said.

It said no casualties were reported on the ground. The report did not say what type of plane was involved or give other details.

Located in the South China Sea, Hainan has multiple military installations geared toward enforcing China's claims over virtually the entire waterway. The claims are disputed by other regional governments and confrontations between their armed forces, and that of the United States, occasionally occur.

A collision between a U.S. Navy surveillance plane and a Chinese fighter in 2001 led to the U.S. aircraft making an emergency landing on Hainan.
