An Indonesian wounded in Thursday’s gun and bomb attacks in Jakarta has died, bringing the death toll to eight including four civilians, police said. Officials originally believed there were five attackers, but later said one man thought to be an attacker was actually a civilian. All of the attackers, including two previously convicted attackers, were killed. At least 20 people were injured, several of them in a serious condition. One of the attackers seen carrying a gun and rucksack during the attacks was named as Afif Sunakim. He was previously given a seven-year jail term for attending a militant camp. The attacks began with a series of bomb blasts at an intersection near a shopping mall and a Starbucks coffee shop. As people inside ran out, two gunmen waiting outside opened fire. At least two attackers also attacked the police box in the centre of the intersection in a suicide bomb attack. The group planned to target government offices and foreigners in other Indonesian cities, a spokesman said.
