JAKARTA, Dec. 17 (Xinhua) -- The Indonesian anti-terror squad of the National Police's Detachment 88 have arrested eight IS-linked militants in the country's easternmost province of Papua and are investigating their terrorist plots, a police officer said here on Tuesday.
The militants have escaped from the chase of the squad in the country's western parts of North Sumatra province and Lampung province, National Police's spokesman Senior Commissioner Asep Adi Saputra said.
Papua province is home to the separatist Free Papua Movement and has been hit by a series of unrests in recent months.
The police are deepening their investigation on the terrorist plots set up by the militants grouped in an outlawed Jemaah Ansharut Daulah (JAD) which has been affiliated with the IS group in Iraq and Syria, according to Saputra.
Authorities will beef up security during Christmas and New Year to prevent possible terrorist strikes, according to the police.
Over 117,000 police personnel and soldiers will be dispatched during the events. Militants had made the events their targets in 2000 that killed dozens of people, they said.
