Indonesia: Trouble Again in Ambon

Clashes on 11 September between Muslims and Christians in Ambon, capital of Maluku province, and sporadic incidents thereafter raised fears of a return to the communal fighting that wracked the region from 1999 to 2002. This time, an extraordinary effort by grassroots “peace provocateurs” and local officials largely kept the violence from spreading further in Maluku. But the unrest triggered efforts by extremists elsewhere to manipulate communal tensions, apparently motivating the bombing of a church in Solo, Central Java on 25 September...
Small incidents, but with potential to flare up further. Relevant to regional terror issues as well. The decline in Islamist influence in Indonesia has been closely linked to the decline in outbreaks of sectarian violence. JI and similar groups there (as elsewhere in SE Asia) have had very little success with the global jihad message, or in rallying support behind issues in Afghanistan or the Middle East: the concern is overwhelmingly with local issues. They have, however, very successfully portrayed these sectarian outbreaks as oppression of Indonesian Muslims.

Hard to say whether this outbreak was orchestrated for this purpose (the date could be coincidence) or was simply a recurring flare-up, but it bears watching, as this sort of violence has a direct bearing on local support for and recruitment by extremist groups.
