Twenty-five years ago today, on the morning of September 20, 1994, Tian Mingjian, a seriously disgruntled PLA officer gunned down 17 people in the center of Beijing including Iranian diplomat Yousef Mohammadi Pishknari and Pishknari’s 9-year-old son. Over 70 people were injured in the gun battle between Tian and Beijing police and army units. The terror ended when Tian was shot by a sniper.
