Police in Hong Kong have used tear gas for the first time in about 10 days to try to break up fresh anti-government protests.
The latest demonstrations took place in the Kwun Tong industrial district of the Chinese-ruled city.
Protesters took to the streets to demand the removal of smart lampposts over fears they could contain high-tech cameras and facial recognition software used for surveillance by Chinese authorities.
Activists, carrying umbrellas in the sweltering heat, filled a main road in the Kowloon peninsula, calling for the government to answer their demands.
Some protesters set up makeshift barricades on a road outside a police station, facing off with police in riot gear.
“Hong Kong people’s private information is already being extradited to China. We have to be very concerned,” said march organiser Ventus Lau.
