Hong Kong: police fire teargas and protesters hurl petrol bombs as violence escalates
Universities and schools close after police shoot protester and man is set on fire
Riot police have fired teargas on anti-government demonstrators gathered in Hong Kongβs central business district and several universities, as protests paralysed the city for a second day in a row.
Protesters built street barricades, set fires and threw petrol bombs, chairs and other objects at police on Tuesday during another day of strikes demanding greater democracy in the Chinese territory.
