The leader of a peaceful protest held by an outlawed separatist group in Indonesia has been jailed for life for treason, a court official says.
Johan Teterisa was among 20 members of the South Moluccan Republic group (RMS) jailed for their part in the protest.
They danced and unfurled a flag of their self-proclaimed republic in front of President Susilo Bambang Yudhoyono in provincial capital Ambon in 2007.
The mainly Christian RMS was set up by loyalists to Dutch rule in the 1950s.
It is not thought to have widespread support in the Moluccas - but analysts say the severity of the sentences shows how Indonesia is keen to stamp out separatist movements.
