Update 17th June:
Given the media blackout on the events, the main source of information is Twitter. Search for and follow updates from #Aluthgama. For those without Twitter accounts check Groundviews, for some updates. There is also a new report from DBS Jeyaraj.
The latest round of violence is the inevitable result of a campaign that started about a year and a half ago. I put up a number of posts on the subject, which I have now tagged under one label for easy access.
There is still a dearth of information but columnist DBS Jeyaraj has put up a summary of the latest events and incidents that on his blog and the Daily FT also carries a report.
