The Easter Sunday bombings in Sri Lanka may have been funded and inspired by Isis, the country’s defence minister, Ruwan Wijewardene, has said. Most of the attackers were “well-educated and come from middle or upper-middle class families”, he told reporters on Wednesday, adding that one of the bombers had studied in the UK and Australia. Police have detained 58 people in connection with the attacks, but warned that up to nine suspects could still be at large and armed with explosives.

Death toll. The death toll from the attacks has risen to 359, with 500 injured. The names of victims have begun to emerge, but in Negombo, the scale of the loss has led to many being buried in mass graves.
