COLOMBO, Sri Lanka — Nine suicide bombers from mostly educated, middle-class backgrounds carried out the attacks in Sri Lanka that killed more than 350 people on Easter Sunday, the authorities said on Wednesday as they warned of an ongoing terrorist threat and continued making arrests. The bombers, one of whom was a woman, were all Sri Lankan, officials said. But the authorities were continuing to investigate whether the Islamic State, which on Tuesday claimed responsibility for the coordinated blasts, had provided more than symbolic support, such as by training the attackers or building the bombs. The authorities said the number of people arrested had risen to 60, and that other individuals involved in the attacks remained at large. arrived to assist in the investigation, the American ambassador, Alaina Teplitz, said there were believed to be “ongoing terrorist plots,” and Sri Lanka’s state minister of defense said the danger had not passed.
