UPDATE: 11:23 a.m. EST — The Islamic State group has officially claimed responsibility for Thursday's attacks in the heart of Indonesia's capital, Jakarta. It's the first time the radical Islamic militant group has targeted Indonesia, the world's most populous Muslim country, according to Reuters.

"A group of soldiers of the caliphate in Indonesia targeted a gathering from the crusader alliance that fights the Islamic State in Jakarta," ISIS reportedly said in a statement Thursday. It added that 15 people were killed in the suicide bombings and gunfight. However, the official casualty count according to the Indonesian government is seven.

Earlier, an ISIS-affiliated news agency reported the group's responsibility for the attacks, but the claim from the group itself provides further confirmation.

The deadly, ISIS-claimed attacks across Indonesia’s capital Thursday will not derail the Southeast Asian country’s long-term economic growth, analysts said. Hours after explosions and gunfire rang out in central Jakarta, killing at least seven people, Indonesia’s central bank cut its benchmark interest rate hours in a bid to shore up the flagging economy, which is growing at its slowest rate in six years.

“The authorities moved quickly to quash the attack. Bank Indonesia (BI) also ensured that monetary transmission continued to function in an orderly manner, so it looks like the effects have been well contained,” Leong Wai Ho, a Singapore-based senior regional economist at Barclays Capital, told Channel NewsAsia in an email Thursday. “There is no impact on growth.”

Euben Paracuelles, Singapore-based executive director and economist at Nomura Securities, agreed that the attacks were “negative news,” but they might not affect the country’s economic growth outlook. Paracuelles expects Indonesia’s economy to expand 5.2 percent this year after sub-par economic growth for most of 2015.

“I think this is going to hurt sentiment in the short term but given the fiscal and monetary support that’s already happening, the gradual recovery we are expecting this year is still intact,” he told Channel NewsAsia in an interview Thursday.

Suicide bombers detonated themselves at sites around Thamrin Street, a major shopping and business district in Jakarta. Indonesian police said the situation is now under control and five alleged attackers were among the dead. A local outfit with ties to the Islamic State group is suspected of carrying out the attacks, according to BBC News.

"We all are grieving for the fallen victims of this incident, but we also condemn the act that has disturbed the security and peace and spread terror among our people," Indonesian President Joko Widodo said Thursday, describing the attacks as an “act of terror.”

The Islamic State group, aka ISIS or ISIL, reportedly claimed responsibility for Thursday's attacks in Jakarta, according to a statement released through one of its allied propaganda agencies.

“Islamic State fighters carried out an armed attack this morning targeting foreign nationals and the security forces charged with protecting them in the Indonesian capital,” Aamaaq news agency said on its Telegram channel.
