An explosion occurred at a mosque located inside the SMAN 72 high school complex in Jakarta, Indonesia, during Friday prayers, resulting in injuries to at least 54 people, primarily students. The police reported that the injuries ranged from minor to serious, including burns, and all injured individuals were swiftly taken to nearby hospitals for treatment, according to SCMP, Channel News Asia, and BBC.

The blasts, which occurred around midday, led to chaos as students and staff evacuated amid gray smoke filling the mosque. Witnesses described hearing two loud explosions coinciding with the beginning of prayers, causing panic and confusion, as reported by Reuters and India Times.

Authorities have identified a 17-year-old male as the suspected perpetrator who is currently undergoing surgery due to injuries sustained during the explosions. The police are investigating the suspect’s background and the nature of the attack, with suggestions that the individual may have had motives related to bullying, according to statements by the Jakarta police chief, Asep Edi Suheri, reported by The Jakarta Post and NPR.

At the scene, police discovered a toy submachine gun with white supremacist slogans inscribed on it, but investigators are urging caution against speculation regarding the explosions being a terrorist act until a thorough analysis is completed. The police action included cordoning off the area while forensic teams gathered evidence, as emphasized in reports from Al Jazeera and LA Times.

The investigation is ongoing, with police currently establishing a timeline for the event and assessing whether the attacks were premeditated. Witnesses' testimonies, combined with video evidence from local media, are expected to play a critical role in understanding the events that unfolded, according to The Jakarta Post and India Times.
