A husband and wife. A pair of brothers from a wealthy, upper-class family. A man with a law degree. Another who studied in the United Kingdom and did postgraduate work in Australia, before coming home to settle down in his native Sri Lanka.
Those are the profiles emerging Wednesday, according to Sri Lankan officials and local media, of the suicide bombers who killed more than 350 people in sophisticated, coordinated attacks on churches and hotels there on Easter Sunday. If the Islamic State's claim of responsibility is true, it would be the group's deadliest terror attack.
