>> It's the third attack Islamic State has claimed in Indonesia this week. Police shot dead four men who mounted an attack on their headquarters using samurai swords on Wednesday. The attack in the city of Pekanbaru killed at least one officer and left two others injured. An earlier police report said one of the men was wearing a suspected bomb vest.
Authorities managed to capture one of the attackers. It's the latest attack after two suicide bombings ripped through Indonesia's second largest city of Surabaya just days before. Two family groups of Islamist militants targeted churches and a police building. In total, they have left around 30 people dead. Children were among the attackers, one of them just eight-years-old.
And as Reuters' Indonesia correspondent Kanupriya Kapoor explains, the families had seemingly led double lives.>> What we do know about them is that they were from relatively affluent backgrounds. They lived in relatively wealthy neighborhoods. Their children went to regular schools. But authorities have said that the children were kept somewhat isolated from the communities, and that they were heavily indoctrinated in radical ideology.
>> Three of the children who survived the attacks told police they'd only interacted with adults who shared a similar ideology. The attacks have shocked Indonesians, prompting calls for more to be done to combat militancy in the world's largest Muslim nation.>> What the authorities intend to do is to go even harder in their crackdown on these militants.
President Joko Widodo has said he is going to accelerate a new anti-terrorism bill that will broaden the definition of terrorism, and allow for preventive detention for longer periods of time. If this bill does not get passed in parliament, as it hasn't been for the past two years, if it languishes in parliament for any longer, President Joko Widodo has said that he would issue a presidential decree allowing authorities to crack down on militant cells.
>> The week's string of assaults is the worst of its kind since the Bali restaurant bombing in 2005.
