evidence: The Catholic Church in Sri Lanka has cancelled all Sunday Masses until further notice. Archbishop of Colombo Malcolm Ranjith said he had seen a leaked security document warning of further attacks. Cardinal Ranjith said that the Church had not been told about intelligence warnings of possible attacks. "We didn't know anything. It came as a thunderbolt for us," he told reporters. [...] Sri Lanka's police chief and top defence ministry official both resigned over the bombings.
