Hundreds of Hong Kong protesters have rallied outside the British Consulate demanding that the UK press China to maintain freedoms agreed when the city was handed over in 1997.
Axar.az reports citing foreign media.
They sang God Save the Queen and waved Union Jack flags.
Thousands are also defying a police ban and marching through the city. Their demands include full democracy.
China has warned other countries not to interfere, saying the situation in Hong Kong is purely its own internal affair.
Britain has said it has a legal responsibility to ensure China abides by the "one country two systems" principle agreed before the handover.
The protesters won a major concession earlier this month when a proposed bill allowing extradition to mainland China, which sparked the latest unrest, was scrapped.
But this has failed to end the unrest as protesters continue to call for democracy and an investigation into allegations of police abuses.
