So reports Sun News Network (Canada); see also National Post (Canada) for a similar story:

One of the organizers of a Gaza peace rally that erupted in violence last week says the group is planning to apologize….

Soon after [a Jewish family that was attacked when they showed up at Calgary City Hall to show support for Israel] arrived, a large group crossed the street from City Hall, some screaming epithets, some going further and attacking.

[Shane Hamilton] was jumped by several people and had to go to hospital with a concussion, scrapes and bruises, and a bite wound on his wrist.

[Hamilton’s] cousin, 20-year-old Jake Birrell, had a shirt bearing the Star of David ripped away and was punched several times, as was Samantha.

Saima Jamal, a member of Justice for Palestinians and one of the rally’s organizers, said the demonstration was always supposed to be peaceful and suggested tensions would have been less frayed had police been there from the start….

An opinion column by Ezra Levant claims that the police were indeed absent: “there was no visible police presence when the protest began.”
