Fifty-five people died in last Sunday's plane crash in Baotou, one more than was originally announced, Chinese investigators said Wednesday.

In addition to 53 people on board the plane, two people on the ground were killed by fragments from the wreck, said Xu Li, deputydirector of the general office of the China Administration of Civil Aviation, at a press conference held Wednesday in Baotou, a city in north China's Inner Mongolia.

Earlier reports said that just one person on the ground had been killed. The newly identified victim was a woman, Gong Xilian,who was doing morning exercises when the plane crashed in city's Nanhai Park.

A 50-seat branch-line CRJ-200 jet, with 47 passengers and six crew members on aboard, crashed into a lake in Nanhai Park shortlyafter it took off Sunday morning.
