Protesters clashed with police at Hong Kong’s international airport on Tuesday evening after flights were disrupted for a second day, plunging the former British colony deeper into turmoil.

The scuffles broke out in the evening between police and protesters, after an injured person was taken out of the main terminal by medics.

Several police vehicles were blocked by protesters, and riot police moved in, pushing some protesters back and using pepper spray at times amid heated scenes.

Protesters also barricaded some passageways in the airport with luggage trolleys and other objects.

Hong Kong’s Airport Authority said operations at the airport had been “seriously disrupted” and that departing passengers had been unable to reach immigration counters.

Hong Kong’s stock market fell to a seven-month low.

Ten weeks of increasingly violent clashes between police and protesters have roiled the Asian financial hub as thousands of residents chafe at a perceived erosion of freedoms and autonomy under Chinese rule.

The United Nations High Commissioner for Human Rights urged Hong Kong to exercise restraint and investigate evidence of its forces firing tear gas at protesters in ways banned under international law.
