JAKARTA, Indonesia — A series of explosions rocked a mosque during Friday prayers at a state high school in Jakarta, leaving at least 54 people injured, predominantly students, according to police reports. The incident occurred at SMA 27, a school located within a navy compound in the Kelapa Gading neighborhood of northern Jakarta. Witnesses recounted hearing at least two loud blasts around midday, coinciding with the start of the sermon. Chaos ensued as students and worshippers fled the mosque, which was quickly engulfed in gray smoke. The majority of the victims sustained injuries ranging from minor to severe, primarily caused by shattered glass. Jakarta Police Chief Asep Edi Suheri indicated that the explosions originated near the mosque’s loudspeaker, though the exact cause remains under investigation. Emergency services transported the injured to nearby hospitals, with 20 students still receiving medical attention, three of whom are in serious condition. Authorities discovered toy rifles and a toy gun near the mosque, prompting further scrutiny. Suheri urged the public to refrain from speculation, emphasizing that the investigation is ongoing and that the findings will be disclosed in due course.
