Taipei's Peace Memorial Park is an oasis of calm in the bustling city, home to morning walkers and lunchtime strollers — along with a camp of indigenous protesters demanding justice.

For several months, the small group has lived in tents in a corner of the park, with a makeshift kitchen and a cluster of painted rocks, photographs and posters tracing the history of Taiwan's indigenous people and their fight for land rights.

They want the repeal of regulation, announced last year, that they say denies their right to ancestral land.
