On 15 August 2005, a Memorandum of Understanding was signed between the Central Government in Jakarta and the separatists in the Province of Aceh, ending 29 years of violence there.
Since then, the media stopped reporting about violence and changed its focus into the adoption of strict Islamic Syariah Law in the province.
Last week, the media has reported about the shoot out between the Police's Anti Terrorist Unit, Densus-88, and a group of fully armed terrorists in Aceh Besar Regency, killing 3 Police officers 2 terrorists and 2 civilians. 13 terrorists were arrested and sent to a detention center in Jakarta.
After the shoot out, a group called the “Tandzim Al-Qoidah Indonesia Serambi Makkah” claimed on its blog: alufuq.wordpress.com that they belong to Al-Qaedah terrorist network. The Police is investigating about the said claim.

Considering that the number of the alleged terrorists were quite big and fully equipped a.o with M-16 automatic rifles, GPS communication, etc. I believe that they must have spent some time to organize themselves.
