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.
Intelligence and Islamic officials believe that political forces are behind what they describe as a shadowy "black campaign" designed to whip up fear that Islam itself is under siege under the leadership of President Joko "Jokiwi" Widodo.

Videos of what police say are fake attacks on Muslim clerics and schools have also been distributed on social media, heightening a mood of unease.
