Hong Kong Chief Executive Carrie Lam on Tuesday said that the violent acts by protesters, paralysing the city's airport the day before, pushed the region to a point of no return and making it a dangerous place.

"The events that took place over the past week have changed the Hong Kong society, it has become unsafe and unstable. Violence and connivance are pushing Hong Kong to where there is no way back and making it a dangerous place ... Yesterday's paralyzed airport, the Cross-Harbour Tunnel blockade, attacks on police stations, Molotov cocktails and smoke bombs attacks have plunged Hong Kong into the vortex of chaos," Lam said while briefing the media about the incident.
