BANDUNG, Indonesia — At least 11 people were killed on Sunday morning after suicide bombers detonated explosions at three churches in Surabaya, Indonesia’s second-largest city, as worshipers gathered between services, the police said.
More than 41 other people were wounded by the attackers, at least one of whom was disguised as a churchgoer, said Frans Barung Mangera, a police spokesman. He said the number of casualties could increase as the police were still investigating the blasts.
Mr. Mangera said the bombs had been detonated in different parts of the city within minutes of one another. He said the victims included many worshipers who were entering and leaving the churches between services. Two police officers were among the victims, he said.
Indonesia’s police chief, Tito Karnavian, said at a news conference that the bombings had been the work of one family, who set off three different kinds of bombs. The forensic laboratory is investigating what kind of explosives were used, he said.
