Voting is underway in the Indonesian province of Aceh, in the second elections there since a peace agreement ended a 30-year separatist war in 2005.
The most important poll is for the post of governor of Aceh, which enjoys considerable autonomy.
The elections are being seen as a contest between two main players - incumbent Irwandi Yusuf, a former rebel who is standing as an independent and Zaini Abdullah, who is backed by the Aceh Party.
The Aceh Party was created by the now defunct Free Aceh Movement, the rebel group that waged a long war for independence from Indonesia.
There are concerns that the bitter rivalry between the two will result in bloodshed after the polls, the BBC reports.
Independent election monitoring agencies have warned that voters in some parts of Aceh may have been subjected to intimidation by both camps.
