Malaysian police have arrested seven men with links to the Islamic State militant group who were planning attacks on non-Muslim places of worship and other targets, authorities said on Saturday.

The Muslim-majority country has been on high alert since gunmen allied with Islamic State carried out a series of attacks in Jakarta, the capital of neighboring Indonesia, in January 2016.

Six Malaysians were arrested in Johor state, north of Singapore, while a seventh, a Filipino member of the IS-linked Abu Sayyaf group, was detained in the eastern state of Sabah, in multiple operations between Feb. 27 and Mar. 15, Inspector-General of Police Mohamad Fuzi Harun said in a statement.
