Fifty-five people, including students and teachers, were injured on Friday in multiple explosions inside a school mosque in Indonesia’s capital during Friday prayers, according to local media.
The explosions occurred in North Jakarta's State Senior High School 72 around 12.30 pm (0530GMT), the Jakarta Globe reported, citing police.
Most of the victims sustained minor, non-life-threatening injuries caused by glass fragments and the impact of the blast’s shockwaves.
A bomb squad carried out a thorough inspection of the area following the incident.
Authorities have yet to determine the cause of the incident. They found a long-barreled firearm and a pistol at the scene, according to the broadcaster tvOne.

The long-barreled firearm was covered with inscriptions, including the name "Brenton Tarrant," the Australian white supremacist behind the 2019 Christchurch attack; the phrases "Welcome to Hell" and "For Agartha," referencing a conspiracy theory about advanced beings secretly ruling the Earth; the year "1189," when the Third Crusade began; and the name "Alexandre Bissonnette," the 2017 Quebec City mosque shooter.
According to the Jakarta Globe, suspicious objects, such as components resembling a homemade explosive device, a remote control, and airsoft and revolver-type firearms, were also discovered near the site.
Police said the investigation is ongoing and that all evidence will be examined by forensic and bomb-disposal experts.
According to Mayndra Eka Wardhana, the spokesperson for the police’s Anti-Terror Detachment 88, an elite anti-terror unit has been deployed to determine whether the incident involved the intentional use of explosive materials.
"Our team is assessing whether any terrorist motive or network was involved," he said.
However, Indonesia National Police Chief General Listyo Sigit Prabowo said that police have identified one suspect as being behind the explosions, according to state-run news agency Antara.
"One of the two individuals undergoing surgery is suspected to be the perpetrator. We are still gathering information to identify the motive behind the explosions," he said, adding that the suspected student has not yet been questioned as he is severely injured.
"The number of victims is between 50 and 60, and a medical post has been set up to treat them. Several have already been discharged," the police chief said and confirmed that no fatalities have been reported yet.
