One London marcher's protest asgainst the Hong Kong police's use of pepper spray against protesters
Demonstrators backing the democracy activists in Hong Kong marched in London on Saturday, as counter-protesters staged a rival rally.
More than a thousand people took part in the two demonstrations in the British capital.
Protesters supporting the activists paraded banners reading "Will Britain hold China to its promise on Hong Kong's freedom?", "Power to the people: stand with Hong Kong" and "Will Boris surrender to China?", referring to new Prime Minister Boris Johnson.
Others said "The only place I want pepper is in my noodle soup", "SOS: please save Hong Kong" and "No China extradition".
The gathering was organised by the StandwithHK and D4HK groups.
The old British colonial Hong Kong flag was seen at the demonstration.
Britain handed control of Hong Kong back to China in 1997 on the basis of the Joint Declaration it signed with Beijing, which guarantees freedoms in the semi-autonomous city until 2047.
Counter-protesters waved Chinese flags and held up signs saying "traitor", "one nation, one China" and "Hong Kong is part of China forever".
Meanwhile in Paris around 50 people -- Hong Kongers but also Chinese and Taiwanese -- demonstrated in support of the protesters in the former British colony, chanting "freedom for Hong Kong" and even "freedom for China".
"Today Hong Kong, tomorrow Asia and the next day Europe," one protester's placard read.
Here again a counter-protest took place with twice as many Chinese waving mainland flags and denouncing the "violence" of "the Hong Kong rioters".
In Hong Kong, democracy activists kicked off a weekend of fresh rallies on Saturday in a major test for the movement following criticism over an airport protest earlier this week -- and as concerns mount over Beijing's next move.
Ten weeks of demonstrations have plunged the international finance hub into crisis, with communist-ruled mainland China taking an increasingly hardline tone.
Hong Kong allows far greater civil liberties than those on the mainland, but the protesters say those freedoms are eroding as mainland Chinese interference grows.
