Hong Kong students leave besieged university campus

The Hong Kong Polytechnic University has been been at the center of a violent standoff between police and protesters in the past week.

On Saturday (November 16) police moved in to clear the campus and the protesters responded with barrages of rocks and Molotov cocktails, leaving parts of the university in flames.

By Tuesday (November 19), there appeared to be only about 100 protesters left at the university.
