Central Java police spokesman Col Liliek Darmanto says police early today arrested 36 men who were attending military-style training at an alleged jihadi camp on the remote slopes of Mount Sumbing.
Police are investigating the men's possible links to Islamic radicalism. Officers seized air rifles, knives, jihadi books and flags in the raid.
Separately, police say five suspected militants were captured late yesterday in Malang, a hilly city in East Java province.
