Sri Lanka's Easter Sunday bomb attacks are believed to be retaliation for a recent attack on mosques in New Zealand, a Sri Lankan official said on Tuesday, adding that two domestic Islamist groups were believed to be responsible.

"The initial investigation has revealed that this was in retaliation for the New Zealand mosque attack," junior minister for defence Ruwan Wijewardene told parliament.

"It was done by National Thawheed Jama'ut along with JMI," he said, referring to another local group, Jammiyathul Millathu Ibrahim.

At least 290 people were killed in the explosions and more than 500 were wounded.
