Indonesian police said Tuesday they had arrested four people after a major raid on a terrorist training camp in a remote region of Aceh province and were pursuing dozens who escaped. Aceh police chief Aditya Warman said some 50 militants were using the camp and "strongly suspected" of being part of regional terror group Jemaah Islamiyah (JI), blamed for multiple attacks across Indonesia.More than 100 heavily armed police took part in the raid just before midnight Monday in a forested part of Aceh Besar district, about 70 kilometres (40 miles) east of the provincial capital Banda Aceh. The militants were conducting military-style training including the use of firearms. Only three were caught in the raid and the rest escaped into the jungle, the police chief said. A police spokesman later updated the number arrested to four.
Police found rifles, Malaysian military uniforms and terrorist propaganda material including videos of the 2002 bombings on the Indonesian resort island of Bali which killed more than 200 people, mainly Western tourists.
"We received information that there were training activities comprising 50 people from a group suspected to be related to Jemaah Islamiyah," Warman said. "The group keeps moving around to avoid police detection. They have moved over four districts.
"We found books on jihad (holy war), CDs on bombings in Bali and other areas, Malaysian military uniforms. There's a jacket with the word 'Jemaah' ('congregation') on it, among other things."
The police chief said operations were ongoing to track down the remaining suspects. "We've known about them since September but we couldn't find them until now," he said, adding that the group included foreigners who were able to "blend in" with locals.
"We're very careful when dealing with this group so we must coordinate with national police," Warman said. "We will continue to chase them."
