News in Indicate that Hong Kong police fired tear gas on Tuesday (Nov 12) in the Central financial district,
over the harbour in Mong Kok and at universities to break up protests which they said were leading the city to the “brink of total breakdown”.
Renewed clashes at university campuses broke out as night fell, with barricades set ablaze and fresh rounds of tear gas whizzing through the air, turning the usually placid hillside campus into a battleground.

As the battle rages on at #CUHK, some protesters have taken over the junction in front of SOGO in Causeway Bay now. Throwing bricks everywhere, paralysing traffic. #HongKong pic.twitter.com/7vIoSgSNRm
