AFP have reported that a top police official alerted Sri Lanka's security officials 10 days ago that churches were threatened by a radical Islamist group, National Thowheeth Jama'ath but it is unclear what action, if any, was taken by police forces following this advisory.

However, no group has claimed responsibility for the blast yet.
