Hearings began last month into the case of five West Papuan independence leaders on trial for treason. They were arrested with hundreds of others when Indonesian troops attacked the Papuan People's Congress on October 19 last year.
The conference had declared the Indonesian-occupied territory an independent state. West Papua was officially annexed by Indonesia's Suharto dictatorship in 1969 in a United Nations-supervised “act of free choice”, in which only 1022 Papuans were allowed to vote.
