Indian intelligence officers contacted their Sri Lankan counterparts two hours before the first attack to warn of a specific threat on churches, one Sri Lankan defence source and an Indian government source said. Another Sri Lankan defence source said a warning came "hours before" the first strike. One of the Sri Lankan sources said a warning was also sent by the Indians on Saturday night. The Indian government source said similar messages had been given to Sri Lankan intelligence agents on April 4 and April 20. Sri Lankan police had been warned weeks ago about a possible attacks by a little-known domestic Islamist group, according to an Indian intelligence report given to Sri Lankan state intelligence services, and seen by Reuters.
