Hong Kong police fired tear gas and water cannon as pro-democracy protesters threw petrol bombs in the latest in a series of clashes that have plunged the Chinese-ruled city into its worst political crisis in decades.
Police fired round after round of tear gas as protesters took cover behind umbrellas between the local headquarters of China's People's Liberation Army and government HQ. Protesters also threw bricks at police.
The water cannon fired blue-dyed water, traditionally used elsewhere in the world to make it easier for police to identify protesters later.
Riot police then marched on foot towards the neighboring Admiralty district, followed by about 20 police cars, where some protesters had thrown fire bombs. Others shone blue and green lasers at police lines.
The violence came on the fifth anniversary of a decision by China to curtail democratic reforms in the former British colony, which returned to China in 1997.
