Several Asian airlines have cut flights to Hong Kong for the coming weeks, an industry scheduling publication showed, as anti-government protests in the city grow increasingly violent and disrupt daily life.

Routes Online said the latest schedules showed cancellations from PT Garuda Indonesia (Persero) Tbk, India’s SpiceJet Ltd., Malaysia’s AirAsia Group Bhd, South Korea’s JejuAir Co. Ltd. and Jin Air Co. Ltd. and the Philippines’ PAL Holdings Inc. and Cebu Air Inc.

The cuts come as Hong Kong police on Monday fired tear gas at protesters trying to escape a besieged university, while others armed with gasoline bombs awaited an expected operation to oust them.
