Pro-democracy protesters blocked passengers at Hong Kong's airport Tuesday, causing further travel chaos a day after triggering an unprecedented shutdown and defying the city's leader who warned against heading down a "path of no return".
The new rally came as Beijing sent further ominous signals that the 10 weeks of unrest must end, with state-run media showing videos of security forces gathering across the border.
The crisis, which has seen millions of people take to Hong Kong's streets, has become the biggest challenge to Chinese rule of the semi-autonomous city since its 1997 handover from Britain.
Hong Kong's pro-Beijing leader, Carrie Lam, gave an at-times emotional press conference on Tuesday morning in which she warned of dangerous consequences if escalating violence was not curbed.
"Violence, no matter if it's using violence or condoning violence, will push Hong Kong down a path of no return," Lam said.
"The situation in Hong Kong in the past week has made me very worried that we have reached this dangerous situation."
"I understand the basics of the protest and they've got a point: it's about freedom and democracy and it's incredibly important."
