NTJ was first made known to the Sri Lankan Police when a police officer sent an announcement to the authorities warning about a possible attack on churches 10 days before the 2019 Sri Lanka Easter bombings on 21 April 2019 . The report read that " the NTJ is planning to carry out suicide attacks targeting prominent churches as well as the Indian high commission in Colombo . " Prime Minister , Ranil Wickremesinghe , remarked that government officials did not receive the advisory and that they would " look into why adequate precautions were not taken . " After the attacks , the Health Minister Rajitha Senaratne confirmed at an 22 April 2019 press conference that all seven of the suicide bombers in the near-simultaneous attacks were Sri Lankan citizens associated with NTJ , but said that foreign links were suspected . Officials earlier blamed the local Islamist group , " National Tawhid " , but Al Jazeera correspondent Samer Allawi said the authorities had denied officially accusing the group of responsibility . Islamic State of Iraq and the Levant ( ISIL ) has claimed responsibility for the attacks
