LAHORE, Pakistan — A radical Islamist party agreed Sunday to suspend for three days its march of thousands toward the capital Islamabad after Pakistan agreed to drop pending charges against the party’s leader.

Party supporters Saturday departed the eastern city of Lahore, clashing for a second straight day with police who lobbed tear gas into the crowd. The group began its journey a day earlier with the goal of reaching Islamabad to pressure the government to release Saad Rizvi, head of the Islamist Tehreek-e-Labiak Pakistan party. Rizvi was arrested last year amid demonstrations against France over the publication of caricatures of Islams Prophet Muhammad.

Raja Basharat, provincial law minister, told The Associated Press that under the agreement Punjab will withdraw charges against Rizvi and release all those detained during the protest march by Tuesday.

Rizvi had been detained pre-emptively on a charge of inciting people to assemble unlawfully. It was unclear when he would be released.

Basharat also said the agreement stipulates that the federal government will honor a previous agreement with the TLP to address diplomatic ties with France over the publication of the caricatures.

Sajid Saifi, spokesman for Rizvis party, confirmed the ministers account and said thousands of party supporters will stay in the town of Mureedke waiting for the release of party leaders and members who have been detained.

Pakistan Interior Minister Shaikh Rashid Ahmed told reporters that the TLP’s demand that the French ambassador to Pakistan be expelled over the caricatures would be taken to a parliamentary committee in the coming days.

Basharat, Ahmed and Religious Affairs Minister Noorul Haq Qadri took part in the talks with the TLP executive council.

Violent clashes erupted between security forces and the Islamists in Lahore killing at least two police and injuring about a dozen, police said. Saifi claimed four party supporters were killed by police fire and many others were injured. Police said the demonstrators torched several police vehicles there.

Ahmed said the government was unaware of any deaths of TLP supporters.

Rizvis party gained prominence in Pakistans 2018 elections, campaigning on the single issue of defending the countrys blasphemy law, which calls for the death penalty for anyone who insults Islam. It has a history of staging violent protests to pressure the government to accept its demands.
