BEIJING - Local authorities in Beijing said Thursday a 66-year-old man who died after crashing his light aircraft into the city's tallest building last week had suicidal thoughts, repeatedly writing in his diary about "ending his life."

The Chaoyang district government in the capital said it had concluded that the incident was caused by "personal reasons," and also disclosed that the 13 people injured were not in life-threatening conditions.
