Hong Kong
protesters struck the city's transport network for a second day running on Tuesday as western powers voiced concern over spiralling violence after
police shot a young demonstrator and another man was set on fire.
The flare-up is the latest in the 24 straight weeks of increasingly violent rallies in Hong Kong, aimed at securing greater democratic freedoms from China.
Small bands of masked protesters blocked roads, threw objects onto rail tracks and held up subway trains, sparking cat-and-mouse clashes with riot police and renewed chaos throughout the day.
