(HONG KONG) — Protesters in Hong Kong trampled a Chinese flag, vandalized a subway station and set a fire across a wide street on Sunday, as pro-democracy demonstrations took a violent turn once again. The day’s action began peacefully, as protesters filled a shopping mall and, in a new twist, folded paper “origami” cranes that they tied onto a large rigging that they assembled in the mall in the Shatin district. Some put a Chinese flag on the floor and took turns running over it, before defacing it and putting it in a dumpster outside, which they then pushed into a nearby river. One group later attacked the Shatin subway station, which is connected to the mall.
