Sri Lanka on Thursday marked the third anniversary of multiple suicide bomb attacks on Catholic churches and tourist hotels on Easter Sunday.

This happened amid complaints that the government had failed to carry out proper investigations.

Catholics organized services in churches throughout the country as members of parliament marked a minute’s silence during their sessions as part of the events to remember the 271 killed in the attacks.

Islamic extremist groups carried out six suicide attacks on churches and hotels on April 21, 2019.

The head of the Catholic Church in Sri Lanka, Cardinal Malcolm Ranjith, has complained that the current government has failed to properly investigate the attacks.

The cardinal said there was a need for the government to find out the motive behind the attacks and the people responsible and those who failed to prevent the disaster.

“The failure to carry out detailed investigations not only on the groups responsible for the suicidal attacks.

“But to go beyond that to probe those persons who failed to act on advance intelligence reports about the possible attacks is regrettable,’’ Cardinal Ranjith told a memorial service in Colombo on Thursday.

A presidential commission has recommended that action should be initiated against former president Maithripala Sirisena for failing to take precautionary action to prevent the attacks.

In spite of the availability of foreign intelligence reports about the plan by Islamic groups.

However, no action had been taken against Sirisena and he currently served as a government member in parliament.
