Hong Kong protests see renewed clashes at university

Police have fired tear gas at protesters holding out at Hong Kong Polytechnic University as overnight clashes resumed in morning.

A large group of people arrived Sunday to try to clean up a debris-strewn roway. Riot police appeared after cleaners were warned away by protesters.

police shot volleys of tear gas toward protesters, who sheltered behind a wall of umbrellas across an entire street.

skirmish came hours after intense overnight clashes in which two sides exchanged tear gas and gasoline bombs. Many protesters retreated inside Polytechnic campus.

Protesters have largely retreated from or major universities that were occupied for much of last week, but a contingent remains at Polytechnic.

Hong Kong’s anti-government protests have been raging for more than five months.
