What Happened: Almost exactly 10 years after the close of its decadeslong civil war, an unprecedented wave of terrorist attacks has struck Sri Lanka. Targeting Easter church services and hotels frequented by foreigners, eight blasts went off in Colombo, Negombo, Kochchikade and Batticaloa, most of which appear to have been carried out using suicide vests and shrapnel. Explosive devices were also found near Colombo's international airport and other areas, but they did not detonate. The bombings killed at least 290 people and injured 500 others. According to official releases, the dead included 31 foreigners, with a further 14 unaccounted for. The U.S. Department of State confirmed that the dead, injured and missing included several U.S. citizens and issued a Travel Warning regarding Sri Lanka, saying additional attacks could occur there.
