Regional terror network Jemaah Islamiah has recovered from the death of its master bomb maker, Malaysian Azahari Husin, and established a wing dedicated to targeting Indonesia's anti-terror police, according to a security source.
The officer also claimed the militants were planning a series of attacks, including assassinations of foreigners and regional officials.
'JI has become stronger and has recovered from Azahari's death. They now have a military wing called Qoriyah, or Askari. This Askari has set up a special unit to fight us, the anti-terror police,' an officer in Yogyakarta said.
'Askari also has plans to kill the leaders of Den88,' he added.
Detachment 88, nicknamed Den88 is the police's anti-terror taskforce set up after the 2002 Bali bombings that killed 202 people, including 11 Hong Kong residents. The US-trained taskforce has arrested more than 300 terror suspects.
Azahari is believed to have made the bombs for all the country's biggest attacks. His death in a police shoot-out in 2005 was hailed as a major blow to JI.
But information gleaned from seven terror suspects arrested over the past two weeks revealed the network's growing strength and ambitions. The arrests led to the seizure of a huge cache of weapons, including 70.5kg of TNT and 217 detonators. Eleven guns, including M16s, and jihad literature were also seized, along with 1,600 rounds of ammunition and what were described as dangerous chemicals.
