NEW DELHI - Indian intelligence officers had prior knowledge of the Sri Lanka attacks, international media has revealed.
Indian officials 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.
Sri Lankan intelligence officials were tipped off about an imminent attack by Islamist militants hours before a series of suicide bombings killed more than 300 people on Easter Sunday, three sources with direct knowledge of the matter said.
Three churches and four hotels were hit by suicide bombers on Sunday morning, killing 321 people and wounding 500, sending shockwaves through an island state that has been relatively peaceful since a civil war ended a decade ago.
Islamic State claimed responsibility for the attacks on Tuesday, without providing evidence of its involvement.
