▶️ Police and protesters clash at Hong Kong Polytechnic University, Saturday, November 16.
👉 Riot police throw tear gas while protesters responded by throwing Molotov cocktails and setting up barricades made of bricks.
Over the past week, some students took over university campuses, many of which were closed early for the semester because of the unrest.
Students at the sites in some cases collected makeshift weapons, such as bricks, slingshots and Molotov cocktails, which they say are used to defend themselves from police attacks.
Dozens of Chinese People's Liberation Army soldiers helped clear protester barricades from a street Saturday, emerging from their barracks for the first time since protests engulfed the semiautonomous Chinese territory five months ago.
Pro-democracy lawmakers immediately condemned the move as a violation of the Basic Law, Hong Kong's mini-constitution, which forbids interference by mainland Chinese soldiers unless the Hong Kong government formally requests action.
