Indonesia's only province ruled by Islamic law went to the polls on Monday to elect its powerful Governor, testing a fragile peace following a 30-year war by separatist rebels.
The elections in Aceh were the second since the province suffered 170,000 fatalities in the Asian tsunami of 2004, and since the war against Indonesian rule ended in 2005, having claimed 15,000 lives.
Irwandi Yusuf, the 51-year-old incumbent who was elected in December 2006, is seeking a second term, with his main challenge coming from the powerful Aceh Party's Zaini Abdullah (71). A survey group said a quick count showed Mr. Abdullah would win.
