Tibet: China celebrates 50 years since 'autonomy' in Lhasa

China has marked 50 years since it established Tibet as what it calls an "autonomous region", by holding a large parade in the capital Lhasa.

The event, which featured large colourful floats and military marches, was attended by senior Communist Party officials.

Foreign news organisations like the BBC were not allowed to travel to Tibet to cover the event.
