Police in Sri Lanka said Monday the investigation into the Easter Sunday bombings will examine reports that the intelligence community failed to detect or warn of possible suicide attacks before the violence.
The nine bombings of churches, luxury hotels and other sites was Sri Lanka's deadliest violence since a devastating civil war in the South Asian island nation ended a decade ago.
Police spokesman Ruwan Gunasekara said Monday the death toll had risen overnight to 290 dead with more than 500 wounded.
Two government ministers have alluded to intelligence failures.
Telecommunications Minister Harin Fernando tweeted, "Some intelligence officers were aware of this incidence. Therefore there was a delay in action. Serious action needs to be taken as to why this warning was ignored."
"People didn't know what was going on. It was panic mode." He added: "There was blood everywhere."
The Archbishop of Colombo, Cardinal Malcolm Ranjith, called on Sri Lanka's government to "mercilessly" punish those responsible "because only animals can behave like that."
