Hundreds of people joined an evening demonstration among Hong Kong's skyscrapers on Thursday marking six months since the city's protest movement began.

The crowd chanted “Hong Kong people, revenge!" in anger at police use of tear gas and widespread arrests.

The “United We Stand” rally came amid concerns from some protesters that the movement is flagging as it enters its seventh month, as the government shows no signs of making further concessions.

It also comes as the government is facing stepped-up pressure to agree to an independent probe of police violence that has angered many in the semi-autonomous Chinese territory.
