Protesters in Indonesia's easternmost province of Papua set fire to tyres and torched a local parliament building after a demonstration against the recent detention of scores of Papuan students.
A separatist movement has simmered for decades in Papua, while there have also been frequent complaints of rights abuses by Indonesian security forces.
The spark for the latest anger appears to have been the detention of scores of Papuan students in Surabaya, East Java, for bending a flagpole during the celebration of Indonesia's Independence Day on 17 August.
