Sri Lanka is moving to curtail Saudi Arabian influence, after some politicians and Buddhist monks blamed the spread of the kingdom's ultraconservative Wahhabi school of Islam for planting the seeds of militancy that culminated in deadly Easter bomb attacks.

On April 21, nine Sri Lankans blew themselves up in churches and luxury hotels, killing more than 250 people and shocking the country a decade after its civil war ended.

Sri Lanka has since arrested a Wahhabi scholar and is poised to take over a Saudi-funded school. The government also says it will monitor previously unchecked money flows from donors, including prominent Saudi families, to mosques on the Indian Ocean island.
