Following the bomb attacks at four hotels, one housing complex, and three Christian churches in Sri Lanka on Easter Sunday -- 290 killed, over 500 injured -- officials there said they believe a radical Islamist group was responsible. Twenty-four suspects are now in custody, according to news reports. Cardinal Robert Sarah, a high-ranking official at the Vatican and a potential future Pope, denounced the "terrible attacks" and declared, "I condemn this barbaric Islamist violence."
