Hundreds of protesters staged a sit-in at Hong Kong’s main international airport terminal on Friday, the first of three straight days of demonstrations after clashes last week triggered fears that a wider confrontation could erupt in the Asian financial hub.

An estimated 200 to 300 people clad in black shirts sat on the ground of Terminal 1’s arrivals hall, holding up signs and chanting slogans including “Free Hong Kong! Free Hong Kong!” as crowds watched from upper floors. Cathay Pacific Airlines Ltd.’s flight attendants’ union encouraged people in the aviation industry to participate and said it would allocate a specific area for its members who attended.

Hong Kong International Airport said earlier in the day that operations would continue as normal, posting a message online cautioning passengers to allow sufficient time to reach the airport and pay attention to updated flight information. There were no signs of service disruptions by afternoon.
