A massive explosion at a commercial building in Logan Township, New Jersey, has left several individuals injured, with reports indicating at least four critically hurt. The blast, which was felt across three states, prompted local authorities to issue a shelter-in-place order for residents within a two-mile radius. Eyewitness accounts describe flames reaching up to 30 feet high, and the sound was so powerful it alarmed people as far away as Delaware. Emergency crews have responded to the site, where injuries are being assessed and residents are urged to stay safe as the situation continues to evolve.
