More than 290 people died and 500 more were injured in explosions at churches and hotels frequented by foreign tourists in Sri Lanka on Easter Sunday — which Sri Lanka's Prime Minister Ranil Wickremesinghe described as "cowardly attacks."
The latest: A Sri Lankan government forensic analyst said 7 suicide bombers caused 6 of the blasts, AP and Reuters report. Police arrested 24 suspects by Monday over the attacks, which killed at least 37 foreigners, including several U.S. citizens. Authorities were warned of possible attacks 2 weeks ago, the government said Monday. The U.S. State Department warned plotters planned more attacks.
