Hong Kong woke to a third consecutive day of travel chaos on Wednesday, following fiery clashes across the city overnight and a violent standoff at a university campus.
On Tuesday, hundreds of black-clad protesters, many of them students, attempted to block riot police from entering the prestigious Chinese University of Hong Kong.
Under a barrage of constant tear gas, protesters hurled bricks and petrol bombs at police.
The eruption of violence at the university follows some of the worst unrest seen in Hong Kong, since anti-government protests began nearly five months ago.
