The bombers died while five other police officers and five civilians were injured in the assault, which left body parts and glass strewn across the road outside the Kampung Melayu terminal in a working-class district.

“We thought this because the explosives were nearly identical to other terror bombings”, National Police Spokesman Sr.

The attack comes just before Indonesia the holy month of Ramadan, which shows a push to “step up activities” before and during this time on the Islamic calendar, said Dr. Sidney Jones, the director of Institute for Policy Analysis of Conflict. Authorities suspect the attacker, killed by police, had links to a radical network sympathetic to Islamic State.

He said the incident may have been inspired by recent terrorist attacks in the British city of Manchester – which took place at an Ariana Grande concert – and in the southern Philippine city of Marawi.

The country has been hit by a series of low-level attacks since, usually claimed by IS-supporting groups, but most have caused little damage.

Police have identified the bombers as Ichwanul Nurul Salam, 40, and Ahmad Sukri, 32, both from West Java province, said Col. Arif Makhfudiharto, chief of the West Java anti-terror squad.

Police and bomb squad sniffer dogs inspect the site of an explosion in Jakarta, Indonesia, Wednesday, May 24, 2017.

Indonesian police said the weapons appeared to be pressure-cooker bombs carried in backpacks.

The two suspects who killed three policemen at a bus terminal in East Jakarta on Wednesday night in a suicide-bombing had ties to the Islamic State (IS) terror group, the police said on Thursday.

Pressure cookers, filled with explosive materials, nails and buck shots, were in the device used by suicide bombers in the twin blasts that went off five minutes apart, Reuters reported.

The attack near a bus terminal in Kampung Melayu also killed three policemen and injured 11 others, including a 17-year-old driver and 19-year-old student.

“Thus we’ve actually been prepared – but we didn’t know when and where it was going to happen”.

Wednesday’s attack, however, matches a more common trend in recent attacks in Indonesia that have targeted police officers and the state security apparatus more broadly.

According to information from the National Counter-Terrorism Agency (BNPT), released earlier this year, more than 500 Indonesians have joined the war in Syria and Iraq (while it is estimated that more than 100 have traveled back to Indonesia after having fought alongside the militant organization).
