The investigation into the bombings on Sunday in Sri Lanka that killed more than 350 people entered a fourth day on Wednesday. What we know about the investigation• Indian intelligence officials warned their Sri Lankan counterparts of the attack just hours before the first bomb was detonated, but the Sri Lankans failed to act. It was the last in a series of unheeded alerts, including an April 4 warning and an April 11 intelligence memo that warned of attacks on churches and named the plotters. • As anger mounted over the intelligence failures, one lawmaker, Wijedasa Rajapakse, called on Wednesday for the arrest and prosecution of two top security officials, and President Maithripala Sirisena asked the two officials to resign. Some had been educated overseas, including one who was an undergraduate at a university in Britain and went to graduate school in Australia.
