A group of protesters that gathered outside a convention centre in downtown London this morning has dispersed.

A crowd of protesters gathered outside the Best Defence Conference at R-B-C Place where they blocked off entrances to the building and locked some doors with bicycle locks.

Organizers said they were demanding that Canada impose an immediate two-way arms embargo on Israel and halt plans to ramp up military spending.

Protesters were also seen physically clashing with event workers.

London police said one person was arrested for property destruction.
