Please read Sumatra: In One Month Authorities Block the Construction of Five Churches, by Mathias Hariyadi, at Asia News.
"From December 16 last until today at least five Christian churches in the province of Jambi, Sumatra (in the western part of the Indonesian archipelago), have been forced to halt construction work due to a blockade imposed by local authorities, under pressure from the Islamic extremist fringe. The latest case - after the four that occurred in December 2013 - dates back to a few days ago in the district of Bungo. As often happens, the order to stop the project issued by the local administration has been motivated by the lack of the infamous IMB, the building permit necessary for the construction of a building, whether religious or civil."
