Hong Kong police fired water cannon and volleys of tear gas to break up protesters throwing petrol bombs and bricks near the Legislative Council building and central government offices on Sunday, the latest in weeks of sometimes violent unrest.
Some protesters threw bricks at police outside the nearby Chinese People's Liberation Army base in the city and tore down and set fire to a red banner proclaiming the 70th anniversary on Oct. 1 of the founding of the People's Republic of China.
One water cannon caught fire after being hit by a petrol bomb. The water cannon fired blue jets of water, used elsewhere in the world to help identify protesters later.
“Police warn the protesters to stop their illegal acts and leave the scene immediately,” police said in a statement.
The Chinese-ruled territory has been rocked by more than three months of clashes, with demonstrators angry about what they see as creeping interference by Beijing in their city's affairs despite a promise of autonomy.
On July 1, the anniversary of the city's 1997 return to China, protesters wearing hard hats, masks and black shirts laid siege to the Legislative Council building and swarmed inside.
Earlier in the day, protesters gathered peacefully outside the British Consulate, calling on Britain to rein in China.
The Sino-British Joint Declaration, signed in 1984, lays out Hong Kong's future after its return to China in 1997, a “one country, two systems” formula that ensures freedoms not enjoyed on the mainland.
“Sino-British Joint Declaration is VOID,” one placard read in the protest outside the British Consulate.
“SOS Hong Kong,” read another.
“One country, two systems is dead,” protesters shouted in English under umbrellas shielding them from the sub-tropical sun, some carrying the colonial flag also bearing the Union Jack. “Free Hong Kong.”
Violence has broken out on previous weekends with protesters trashing metro stations and setting fires in the streets. The police have responded with tear gas, rubber bullets and water cannon.
The spark for the protests was planned legislation, now withdrawn, that would have allowed people to be sent to mainland China for trial.
The protests have since broadened into calls for universal suffrage.
