Hong Kong police ended their blockade of a university campus after surrounding it for 12 days to try to arrest anti-government protesters holed up inside.
Police removed a stash of nearly 4,000 gasoline bombs left behind by protesters, who fought pitched battles about two weeks ago with riot officers on surrounding streets.
The standoff at Hong Kong Polytechnic University was one of the most dramatic episodes in nearly six months of unrest that began in June with a huge march against an extradition bill seen as an erosion of freedoms promised when the former British colony returned to Chinese control in 1997.
Protesters have since expanded their demands to include fully democratic elections and an investigation into police use of tear gas, rubber bullets and other force to suppress the violence. Police have arrested 5,890 people since June, ranging in age from 11 to 83.
