A Hong Kong radio station that has aired pro-democracy shows without a licence for nearly 18 years holds its last broadcast, citing difficulties operating in a "dangerous" political landscape. Founded by veteran activist Tsang Kin-shing in 2005, Citizens' Radio began as an act of civil disobedience against Hong Kong's public broadcasting laws, which he and fellow activists criticised as overly restrictive of public access to the airwaves. "Hong Kong's political situation today has fallen off a cliff," Tsang tells reporters before the final show. "We have no choice but to stop broadcasting." IMAGES AND SOUNDBITES
