A Sri Lankan official says the devastating Easter bombings were retaliation for recent deadly attacks on mosques in New Zealand, as Islamic State claimed responsibility for the coordinated blasts that killed 321 people.
Islamic State's claim, issued on its AMAQ news agency, came shortly after Sri Lanka said two domestic Islamist groups, with suspected links to foreign militants, were believed to have been behind the attacks at three churches and four hotels, which wounded about 500 people.
Islamic State gave no evidence for its claim. The government has said at least seven suicide bombers were involved.
