Police in riot gear were seen lining the streets of downtown Montreal.
What began as a pro-Palestinian gathering at Phillips Square quickly consumed central downtown. Chanting protesters, many of them masked, moved down Ste-Catherine St., with police in riot gear containing them on either side.
Meanwhile, a message blared over police loudspeakers, ordering the crowd to disperse and declaring the protest unlawful.
Physical clashes broke out between officers and protesters, with police firing what appeared to be a chemical irritant on multiple occasions.
Most of the protesters left by 9:45 p.m., many of them departing via the métro.
Reached by The Gazette around 10:15 p.m., the Service de police de la Ville de Montréal could not yet confirm whether there were any arrests or injuries.
This is a developing story. More to come.
