On Friday, the Sri Lankan government ordered mosques to clamp down on extremists and to submit copies of sermons in new fallout from the Easter suicide bombings that left 258 dead.
The country has been on edge since the April 21 attacks by jihadist bombers who attacked three churches and three Colombo hotels which also left 500 people wounded.
The Ministry of Muslim Religious and Cultural Affairs said mosques must not be used for radicalising congregations.
“In view of the prevailing situation in the country, the ministry directs all trustees of mosques not to engage in or permit any gathering to promote or propagate hatred or extremism in any form,” the ministry said.
It said all mosques must submit copies of sermons given within their premises.
