The 70th anniversary of Communist Party rule in China was “one of Hong Kong’s most violent and chaotic days”, the city’s police chief has said.
An 18-year-old protester was shot in the chest with a live bullet – one of six live rounds fired by police.
Protesters – some armed with poles, petrol bombs and other projectiles – fought pitched battles with police in several parts of Hong Kong.
In all police made 269 arrests, more than on any day since protests began.
Those detained ranged in age from 12 to 71. More than 100 people were taken to hospital and 30 police were injured.
Tuesday’s unrest saw police fire 900 rubber bullets and 1,400 rounds of tear gas. That compares with 1,000 tear gas canisters fired in the first two months of protests.
In the days leading up to the anniversary, tensions were high in Hong Kong, which always sees protests on National Day.
This year, however, Hong Kong has seen four months of protests sparked by proposed changes to an extradition bill. Though the changes have been abandoned, the unrest has continued, expanding into demands for greater democracy.
The shooting of Tsang Chi-kin, who was attacking an officer with a pole, was captured on video and shared online.
“My chest is hurting, I need to go to hospital,” said the 18-year-old, who was arrested after being shot. The government said he was now in a stable condition.
Although people have been shot with rubber bullets in previous protests, this was the first injury from a live round.
Police chief Stephen Lo said firing the bullet was “lawful and reasonable” as the officer thought his and colleagues’ lives were under threat.
Asked why the bullet was fired at close range, Mr Lo said: “He [the officer] did not decide the distance between him and the assailant.”-BBC
