The firing of tear gas came shortly after demonstrators — who traveled 150 kilometers (93 miles) from the restive northwest — began arriving and gathering near Islamabad. They defied a lockdown, previous tear gas and widespread arrests despite a ban on rallies in the city. The government was in talks with Khan’s party to avoid any further violence, officials said. Video on social media showed Khan supporters donning gas masks and protective goggles. Protesters on Sunday night burned trees as police fired tear gas to disperse the crowds.
