Rival political parties in the Indonesian province of Aceh signed a peace deal with the government nine years ago. But now they are fighting between themselves ahead of the country's parliamentary elections.

Human rights groups say there have been more than 50 politically motivated attacks this year, as tensions rise between groups that once fought together against the central government. Most members of Aceh's two main parties are former fighters.
