Three officials of the Airport Security Forces (ASF) were reportedly injured.
Workers, holding bamboo sticks and chanting slogans, seemed to lose all control and tried entering the passenger lounge. ASF personnel and the police reached the site to calm the workers and tried to restore order in the area.
Passengers at the airport were stuck inside while authorities made their utmost efforts to restore order.
The workers, however, cooled down once PPP's provincial leadership reached the airport and pacified them. They were seen dancing to the beat of drums and waved flags.
Wattoo and other PPP leaders, including General Secretary Kaira and Firdous Ashiq Awan, arrived at the Lahore airport and are heading to Nasir Bagh to address a rally.
