The Sinhala Ravaya, another shadowy Buddhist supremacist organisation that works with the BBS has reportedly carried out a "raid" on a house in Nawala.
Meanwhile, the Ceylon Today newspaper reported that two raids took place on catholic religious centres in Nawala and Galle, in addition to the raid on the house in Nawala.
The Centre for Policy Alternatives has recorded 65 instances of attacks on places religious worship since May 2009, the vast majority being Christian. Skimming that report, my impression was that most of the attacks were small and concerned localised disputes.
With the involvement of the Sinhala Ravaya and the BBS, I think we are moving in the direction of a centralised, organised, campaign against all things deemed to be non-buddhist and non-Sinhala.
Update: A pastor threatened by a mob in Weeraketiya.
