Sri Lanka admits 'major intelligence lapse'
Sri Lanka has admitted a "major intelligence lapse" before the Easter Sunday bomb attacks which killed 359 people and wounded more than 500.
An Indian intelligence warning from the beginning of the month about planned attacks was not properly shared by the authorities, parliament heard.
President Maithripala Sirisena has moved to sack the defence secretary and inspector general of police.
Eight of the nine attackers have been identified as Sri Lankan citizens, BBC reports.
The government is investigating whether the Islamic State (IS) group was involved in the attacks which targeted churches and high-end hotels.
It has emerged that one of the attackers once studied in the UK and Australia before returning to Sri Lanka.
