A spate of mysterious attacks on Islamic clerics, schools and mosques in Indonesia in recent weeks has ramped up tensions as the world’s most populous Muslim-majority country heads into provincial elections and a presidential poll next year. National police chief Tito Karnavian said during a speech on March 4 at a Muslim boarding school in Banten Province that 45 reports have already been made this year. However, only three of these cases — one in East Java and two in West Java — have been confirmed as targeting clerics. Indonesian police have arrested members of the Muslim Cyber Army (MCA), a cluster of loosely connected groups accused of using social media to attack the government and stoke religious extremism.
