An eyewitness to the deadly twin suicide bombings in East Jakarta last night told a local television station that he heard two explosions at a Transjakarta bus stop near the Kampung Melayu bus terminal, the Jakarta Post reported.
"We suspect this action was planned to attack the police", Sitompul said, adding approximately 60 officers were on duty at the scene.
No group has claimed responsibility so far, he said.
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.
"While security agencies in the region have done well in curbing militancy, they need to be vigilant as we will never know where and when the next strike will take place", he said.
Teten Masduki, chief of staff to Indonesian President Joko Widodo, visited the victims of the attack at the Premier hospital on Thursday morning to give his condolences.
The government has carried out a sustained crackdown on militants since the 2002 Bali bombings by al-Qaida-affiliated radicals that killed 202 people. Gen. Syafruddin has confirmed that the explosions were likely due to two suicide bomb detonations and that there were six victims. We assume that the terrorist targeted those police officers who were at the bus station to secure an approaching parade organized to welcome the start of the holy month of Ramadan (fasting month).
A bomb squad was investigating the explosion as heavily armed police guarded the area.
Eight people were killed, including four attackers, in a terror attack in Jakarta in January 2016.
But with police crackdowns neutralizing numerous country's major terrorist cells in recent years, attacks have tended to become far smaller in scale and directed at police officers - especially unarmed ones directing traffic. But as evidence mounts following a fact-finding mission by local law enforcement and counterterrorism forces, the most important issue is whether the incident shows how terrorist attacks have become so widespread that they are unpredictable.
The bombs used in Wednesday's attacks were made from pressure cookers, similar to a device used in an attack by a JAD militant in the Indonesian city of Bandung in February. Two people were killed, and 24 were wounded. "There was a 10-minute gap between the two explosions".
