Hospital officials say a girl on the Asiana Airlines flight has died from her injuries, becoming the third casualty of the crash in San Francisco.

Dr. Margaret Knudson, San Francisco General Hospital's chief of surgery, said the child died Friday of her injuries.

The girl had been in critical condition since arriving at the hospital Saturday after the plane crashed, killing two others and leaving others in critical condition.

Officials did not identify the girl at the request of her parents. Her age also was withheld.
