A suicide bomber detonated an explosive devise in front of the Surakarta Police headquarters in Central Java on Tuesday, injuring a police officer, said a police representative. The unidentified suicide bomber is reported to have died from injuries sustained during the attack. A motorcyclist attempted to break through a security barricade and, when an officer attempted to stop the approach, detonated a bomb, explained the Surakarta Police spokesperson. 

The alleged attack occurred a few hours after a series of bombings were set off in three cities in Saudi Arabia, including Madinah, considered a sacred Islamic site. The attacks in Saudi Arabia, which left four people dead, followed a bloody week of bomb attacks in Turkey, Bangladesh and Iraq. 

The authorities are still investigating the motive behind the attacks. It is believed that the Islamic State (IS) militant group, which has vowed to step up attacks outside of Iraq and Syria, may have been responsible. 

Meanwhile, State Intelligent Body (BIN) has claimed the Islamic State (IS) militant group is responsible for the suicide attack carried out near the Surakarta Police headquarters in Surakarta, Central Java.

According to BIN’s chief, Sutiyoso, BIN agents claim to have identified a number of IS militant group sympathizers across the country and there is a concentration of sympathizers located in and around Surakarta that are thought to be preparing attacks.  “There are a number of IS sympathizers here who decided not to depart for Iraq and Syria. Instead, they aim to target police and intelligence personnel here,” Sutiyoso said during a phone interview with Metro TV.  The latest attack, according to Sutiyoso, was a part of the IS global terror strategy. “They have been defeated in several countries,” he asserted.

Nur Rohman, 30, identified as the suicide bomber who attacked the Surakarta Police headquarters in Central Java this morning, is alleged to have been affiliated with a local offshoot of the Islamic State (IS) militant group. The group is led by Arief Hidayatullah, whose patron Bahrum Naim was among the masterminds behind the attack that killed four civilians and four perpetrators in Jakarta on Jan. 14, a source has said. 

Nur was the only member of the group to have escaped arrest during a series of raids carried out in December last year by the National Police in which dozens of terrorist suspects were rounded up in several areas in Java, including the Greater Jakarta area, a source at the National Counterterrorism Agency (BNPT) said on Tuesday. The group had allegedly planned to launch an attack on New Year’s Eve revellers. 

While the group's field commander Arief Hidayatullah was arrested, his patron Bahrum Nain fled the country to join the IS movement in Syria. Police believe that Bahrum, along with IS spiritual leader in Indonesia Aman Abdurrahman, directed and financed their followers to launch the attack that was carried out earlier this year on Jl. Thamrin in Central Jakarta.

Whilst, the director of the Jakarta-based Institute for Policy Analysis of Conflict (IPAC), Sidney Jones has warned mid a string of suicide bombings in numerous countries, a terrorism threat was rising threat from the Islamic State (IS) group, especially in Southeast Asia.

She pointed to the recent grenade attack on a pub in Puchong, Kuala Lumpur, as one of numerous terrorism warning signs, particularly as it marked the first attack in the name of IS on Malaysian soil.Tuesday's suicide bombing near Surakarta Police headquarters in Surakarta, Central Java, believed to have been carried out by an IS supporter, was also evidence of IS' growing influence in the region, Jones said. "As IS comes under more pressure in the Middle East, it wants to see more attacks elsewhere," Jones told The Jakarta Post on Tuesday.

IS’ Ramadhan killing spree across numerous countries follows a call by the group's spokesperson, Abu Muhammad Al-‘Adnani, who had ordered IS followers to "make it a month of calamity everywhere for the non-believers". The order was conveyed in a video circulated on the internet in May.

Throughout the fasting month, IS supporters killed more than 800 civilians in numerous attacks, from the massacre at a gay club in Orlando, US, to Sunday's attack in Baghdad that claimed more than 200 lives and the recent suicide bombing near the Prophet Muhammad's Mosque in the Saudi Arabian city of Medina.

While the government had advised people to keep vigilant in public places, airports remained most vulnerable to terrorist attacks, Jones said. Therefore, officials should conduct an emergency security review to identify and fix shortcomings.

She added that inter-agency cooperation between security bodies, including the National Intelligence Agency (BIN), the Indonesian Military (TNI) and the National Police was of utmost importance to identify and tackle terrorist movements these days

I think Sidney Jones’s opinion is true. A lesson learnt from a terror attacks at Surakarta Police headquarter has warned that the revise of the law on antiterrorism must be done quickly with an essence to strengthen our national commitment to combat a terror act has never been gived up and we were never surrendered to terror group’s.

The National Intelligence Agency (BIN), the Indonesian Military (TNI) and the National Police must uphold our national willingness against a terror group’s has never been finished before a terror group’s and their symphatizers has been captured dead or alive.

The rivise of the law on antiterrorism must be completed with BIN’s authority expanded including the authority to catch who allegedly linked to a terror’s group or to strengthen our early detection effort to minimalize a terror threat. The expand of BIN’s authority must be given because a terrorism threat was rising threat from the Islamic State (IS) group, especially in Southeast Asia.

I think all circles in Indonesia don’t make a polemic on BIN’s authority must expand at the revise of the law on antiterrorism plan because Indonesia’s human security at a dangerously nowdays.

Togetherness, we must make a common commitment which judged that a terror’s group, lone wolves and their symphatizers as a common enemies and we’re never give up and surrender to them.
