Intelligence warned of terror attack in Sri Lanka 

Sri Lanka police had alerted the nation about ten days before Sunday's serial blasts that terrorists would target prominent churches across the island nation. Security had also been increased shortly after the alert.

The police were also alerted about a suspected suicide bomber in Colombo. Foreign intelligence agencies had warned Sri Lanka about suspected `jammat' activity.

Six serial blasts rocked Sri Lanka early on Sunday morning. The explosions hit three churches and three luxury hotels in Colombo and other parts of the country, killing 185 people.
