Indonesian police arrested six men in Batam on Aug. 5 who they claim were planning to fire a rocket at Singapore under the direction of a known Islamic State member. Part of Indonesia’s Riau Islands province, Batam is about 16 kilometers (10 miles) across the Singapore Strait from Singapore, to which it is linked by ferry service.
