Protesters took to Hong Kong streets on Sunday to march for press freedom. The demonstration was organised by journalists as fears grow that free expression is being restricted.
Organisers estimated 6,000 took part in the march, with many wearing blue ribbons as a symbol of free expression in the media.
There have been mounting concerns that the mainland is seeking to tighten control over Hong Kong - and rein in its press.
"Headlines have been edited, interviews were barred, and columnists were fired. We have to see this from the context of tightening control on media in Hong Kong," Shirley Yam, vice-chairwoman of the Hong Kong Journalists Association, said at the rally.
Protesters chanted slogans such as "Free the people. Free Hong Kong. No censorship", as they marched through the streets.
This month, two international organisations expressed concerns over the status of press freedom in Hong Kong.
The New York-based Committee to Protect Journalists said media freedom in Hong Kong was currently "at a low point", citing self-censorship among reporters, financial and physical threats against the media, and legislative steps that could hinder investigative reporting.
Meanwhile, Paris-based Reporters Without Borders said Hong Kong's media independence "is now in jeopardy".
Martin Lee, former Democratic Party chairman, who attended the rally, said: "When the freedom of the press is gone, no other freedom can be saved."
The city's government, led by pro-Beijing leader Leung Chun-ying, has denied any attempts by the authorities to suppress the press.
