Police in Hong Kong used tear gas and water cannon against demonstrators during protests on the 70th anniversary of the People’s Republic of China. In one incident, a police officer shot an 18-year-old protestor in the chest, leaving him bleeding. A police spokesperson said the officer feared for his life. She said the person was taken to a hospital for treatment. She provided no other information. Officers have fired warning shots in the air before, but this is the first report that a protestor has been shot. A video of the incident appeared on CNN news broadcasts. Hong Kong’s hospital authority said 51 people were injured in all, two in critical condition.
