Colombo: An initial probe into deadly suicide bomb attacks in Sri Lanka that killed more than 300 people shows it was “retaliation for Christchurch,” the country’s deputy defence minister said on Tuesday.

“The preliminary investigations have revealed that what happened in Sri Lanka (on Sunday) was in retaliation for the attack against Muslims in Christchurch,” state minister of defence Ruwan Wijewardene told parliament.

Fifty people were killed in shooting attacks on two mosques in the New Zealand city of Christchurch on March 15.

Meanwhile, UNICEF spokesman Christophe Boulierac has said there were 45 children among those killed in Sri Lanka’s Easter Sunday bombings.

The death toll rose to 310, including 10 Indians, police said. Over 500 people were also injured in eight blasts targeting three luxury hotels and three churches across three Sri Lankan cities besides two other locations in Colombo, police spokesman Ruwan Gunasekara said in a statement.

As an official mass funeral ceremony for the victims was held on Tuesday, a day of national mourning, the Indian High Commission here put the death toll for Indians at 10.

“Regret to confirm the deaths of two more Indian nationals, A. Maregowda and H. Puttaraju, in the blasts in Sri Lanka, taking the total number of Indian deaths in the tragedy to 10 as of now,” the mission tweeted.
