HONG KONG—Hong Kong police laid siege to a university on Nov. 18, firing rubber bullets and tear gas to pin back pro-democracy protesters and stop them from fleeing amid fears of a bloody crackdown.
Dozens, choking on the tear gas, tried to leave the Polytechnic University by breaking through police lines after a night of mayhem in the Chinese-ruled city in which roads were blocked, and a bridge was set on fire.
