Hong Kong’s airport reopened on Tuesday but its administrator warned that flight movements would still be affected, after China said protests that have swept the city over the past two months had begun to show the “sprouts of terrorism”.
Some flights resumed but many others were cancelled. Hong Kong flag carrier Cathay Pacific said it had cancelled more than 200 flights into and out of the airport on Tuesday, according to its website.
The abrupt shutdown of one of the world's busiest hubs came after thousands of black-clad demonstrators flooded the airport for a peaceful rally.
It was a dramatic escalation of a 10-week crisis that has been the biggest challenge to Chinese rule of Hong Kong since the 1997 British handover.
The protests have infuriated Beijing, which described some of the violent demonstrations as "terrorism".
Washington overnight urged all sides to refrain from violence, as the crisis sparked by a bill to allow extradition to mainland China continues with no apparent end in sight.
