Three people were arrested after pro-Palestinian, anti-NATO protesters smashed windows, clashed with police officers, and set vehicles ablaze on Friday evening.

The protest coincided with the arrival of approximately 300 delegates from NATO member states and partner countries attending a high-level summit, running from Nov. 22 to 25 in Montreal, focused on Ukraine, climate change, and the alliance’s future. The protest also came as the second day of the wave of student-wide pro-Palestinian protests across Montreal.

An initial group of protesters gathered at Émilie-Gamelin Parc downtown at around 4:30 p.m. before marching toward the Quartier des Spectacles, according to Manuel Couture, a spokesperson for the Montreal police. By 5:30 p.m., another group had converged at Place des Arts, and the two demonstrations merged.

The protesters then marched down St-Urbain St. At 6:10 p.m., tensions escalated as demonstrators set an effigy of Israeli Prime Minister Benjamin Netanyahu on fire in the middle of the crowd. As the march continued, objects — including small explosive devices and metal items — were hurled into the street, targeting police officers. By 6:40 p.m., protesters had smashed shop windows near St-Urbain and René-Lévesque Blvd., and set two vehicles ablaze.

Couture said police deployed chemical irritants and conducted crowd-dispersal manoeuvres to regain control. Three protesters were arrested for allegedly assaulting police officers and obstructing police work.

Couture said that the protesters had dispersed by 7 p.m.

The protests come amid heightened tensions following Thursday’s pro-Palestinian demonstrations at Concordia University, where protesters flooded the Hall Building and clashed with pro-Israel counter-demonstrators outside.
