Sri Lanka's Defence Minister Ruwan Wijewardene on Tuesday said that the Easter Sunday suicide bombings which killed 310 people were a response to the mass shooting at mosques in Christchurch in March.

Wijewardene told a special sitting of Parliament that investigations had shown that "this attack was carried out in retaliation for the attack against Muslims in Christchurch" that left 50 people dead.

Mass funeral held for Sri Lanka blasts victims

The first mass funeral was held in Sri Lanka on Tuesday as the country marks a day of mourning for the victims of the Easter Sunday bombings that killed 310 people.

The mass funeral was held at the St Sebastian's church in Negombo, north of Colombo, which was one of the places targeted in Sunday's blasts, reports the BBC.

Earlier, a moment of silence was observed at 8.30 a.m., reflecting the time the first of six bombs detonated.

Flags were lowered to half-mast and people bowed their heads in silence in respect to the victims as well as the 500 people injured in the attacks, BBC said.

The funeral comes amid a state of emergency which was imposed on Monday.

The police have so far detained 40 suspects in connection with the attacks, a spokesman said on Tuesday.

No group has claimed responsibility for the attacks but the government has blamed a local Islamist group for the carnage.

The Foreign Ministry said it had identified 31 foreign nationals among the dead, including 10 Indians, while 14 others remained unaccounted for.
