LAHORE, Pakistan -- Violent clashes erupted between Pakistan's security forces and Islamists in the eastern city of Lahore on Friday, killing at least two policemen and two demonstrators, a police spokesman and witnesses said.
The incident happened after thousands of Islamists launched their “long march" from the city toward the capital, Islamabad, demanding that the government release the leader of their outlawed party.
The rallygoers had set out for Islamabad to pressure the government to release Saad Rizvi, the head of the Tehreek-e-Labiak Pakistan party. Rizvi was arrested last year amid demonstrations against France over publishing caricatures of Islam’s Prophet Muhammad.
Pakistan has deployed police and paramilitary personnel to prevent the demonstrators from leaving Lahore. Authorities also suspended cellular service in parts of Lahore and blocked roads.
The situation worsened when police tried to stop the rallygoers, witnesses said.
The violence disrupted normal life in parts of Lahore, where residents were facing problems in reaching home because of the closure of some roads and continued clashes between police and Islamists.
Rizvi's party said they were peaceful and that police suddenly started firing tear gas shells.
Sajid Saifi, a spokesman for Rizvi's party, blamed police and paramilitary forces for initiating the violence. He said the use of force by authorities killed at least two demonstrators and injured hundreds of people. Some were having a breathing problem because of the use of tear gas, he added.
Saifi alleged that police were not allowing them to transport their injured supporters to hospital. According to witnesses, rallygoers were still walking towards a highway leading to Islamabad.
Police did not immediately respond to a request for comment.
Supporters of Rizvi's party shared videos showing police firing tear gas shells as some of the injured protesters waited for medical aid.
Police spokesman Rana Arif said two of the police officers were killed and another was injured when protesters threw stones. Rizvi's supporters said several protesters were wounded when police swung batons and fired tear gas.
Shipping containers were also being brought in to block the main Islamabad highway and surrounding roads to keep protesters from entering the capital from other nearby cities, towns and villages. Lahore is located about 350 kilometers (210 miles) from Islamabad, and most of the rallygoers are walking, although they had arranged buses and cars to reach the capital in a convoy.
The TLP has a history of staging protests and sit-ins to press their demands.
On Friday, Rizvi's party leader Ajmal Qadri said his supporters launched the “long march" after talks with the government failed to secure Rizvi's release.
The latest development comes at a time when Prime Minister Imran Khan was visiting Lahore.
