India relayed three specific warnings about possible terror attacks to Sri Lanka, ahead of the Easter Sunday bombings. The final warning was communicated just one hour before the explosions started, a person with knowledge of the information told CNN.
The first warning was communicated on April 4; the second warning was sent on April 20, one day before the attacks; and a third warning was sent on the morning of the attack.
The warnings specified that churches and hotels could be among the targets, the person said.
Sri Lankan officials have acknowledged that their country received intelligence about possible terror strikes ahead of the Easter Sunday attacks, but both the President and Prime Minister have said that they did not receive the information.
