Panic and smoke filled a Jakarta navy school compound after an explosion ripped through a mosque during Friday prayers. At least 54 people, including students and teachers, were injured as worshippers scrambled for safety. Bomb squads and anti-terror units rushed to the scene, uncovering wires, remotes, and toy guns but ruling out any confirmed terror link so far. Investigators are probing whether an electrical fault, malfunction, or hidden device triggered the blast. As the area remains under tight security, questions mount over what really caused the terrifying explosion.
