A family of six launched suicide attacks on Christians attending Sunday services at three churches in Indonesia\’s second-largest city of Surabaya, killing at least 13 people and wounding 40, officials said.
Indonesia, the world\’s largest Muslim-majority country, has seen a recent resurgence in homegrown militancy and police said the family who carried out Sunday\’s attacks were among 500 Islamic State sympathizers who had returned from Syria.
"The husband drove the car, an Avanza, that contained explosives and rammed it into the gate in front of that church," East Java police spokesman Frans Barung Mangera told reporters at the regional police headquarters in Surabaya.
The wife and two daughters were involved in an attack on a second church and at the third church "two other children rode the motorbike and had the bomb across their laps", Mangera said.
The two daughters were aged 12 and 9 while the other two, thought to be the man\’s sons, were 18 and 16, police said.
Police blamed the bombings on the Islamic State-inspired group Jemaah Ansharut Daulah (JAD).
JAD is an umbrella organization on a U.S. State Department terrorist list that is estimated to have drawn hundreds of Islamic State sympathizers in Indonesia.
Islamic State claimed responsibility for the attacks, in a message carried on its Amaq news agency.
"This act is barbaric and beyond the limits of humanity, causing victims among members of society, the police and even innocent children," President Joko Widodo said during a visit to the scene of the attacks.
Indonesian terrorism analyst Rakyan Adibrata said it was the first time children had been involved in attacks in the country.
East Java police spokesman Mangera said at least 13 people had been killed and 40 had been taken to hospital, including two police officers. He called on people to remain calm.
Streets around the bombed churches were blocked by checkpoints and heavily armed police stood guard as forensic and bomb squad officers combed the area for clues.
Television footage showed one church where the yard in front was engulfed in fire with thick, black smoke billowing up. A large blast was heard hours after the attacks, which Mangera said was a bomb disposal squad dealing with a device.
The attacks are the deadliest in Indonesia linked to Islamic State and the worst since October 2005, when three suicide bombers blew themselves up in Bali restaurants killing 20.
They came days after militant Islamist prisoners killed five members of an elite counter-terrorism force during a 36-hour standoff at a high-security jail near Jakarta.
Police Chief Tito Karnavian told reporters that because many militant leaders had been captured "these groups are starting to … retaliate."
Wawan Purwanto, communication director at Indonesia\’s intelligence agency, said the main target of militants remained the security forces, but "there are alternative (targets) if the main targets are blocked".
At St Mary\’s catholic church, the first place of worship to be attacked, the bombing happened after an earlier mass was over and when the church was getting ready to hold another service.
Separately, an internal police report reviewed by Reuters said a suspected bomb exploded in a car in the parking lot of a Pentacostal church, setting alight dozens of motorbikes.
In the third location, the Indonesian Christian Church, veiled women entered the church\’s yard where they were stopped by a security guard before an explosion occurred at the same spot, according to the police report.
POPE OFFERS PRAYERS
Jeirry Sumampow, a spokesman for Indonesia\’s church association (PGI), called on the government for more help for security at churches.
Pope Francis offered his prayers for the victims.
"I am particularly close to the dear people of Indonesia, especially to the communities of Christians of the city of Surabaya, which were hit hard by the serious attack on places of worship," he said during his Sunday prayer in Rome.
"Together we invoke the God of peace (asking him) to cease these violent actions and (to make sure) that in the heart of all there could be a space not feelings of hatred and violence, but of reconciliation and fraternity."
Nearly 90 percent of Indonesians are Muslim, but the country is also home to sizeable communities of Hindus, Christians, Buddhists, and people who adhere to traditional beliefs.
Indonesia has had some major successes tackling militancy inspired by al Qaeda\’s attacks on the United States in 2001. But there has been a resurgence of Islamist attacks in recent years, including in January 2016 when four suicide bombers and gunmen attacked a shopping area in central Jakarta.
Churches have also been targeted previously, including near-simultaneous attacks over Christmas in 2000 that killed about 20 people.
