China denies blockading monastery where monk burnt himself

Tibetan exile groups have released video footage which they claim shows a young monk who burnt himself to death last month in a protest against China's government.

The groups say the footage also shows a security build-up that followed.

China has admitted that a young monk died and that there were clashes but has denied blockading the monastery.
