Emergency crews rushed to the New Seabury Country Club in Mashpee on Cape Cod late Wednesday afternoon after a fireworks explosion injured several people, according to local and state authorities. The incident occurred on the golf course where a permitted Independence Day–week display had been scheduled for 9 p.m. State Police fire investigators and compliance officers from the Massachusetts State Fire Marshal’s Office arrived on scene, and aerial images showed spent pyrotechnic equipment and scorched grass. Officials have not disclosed the number or severity of the injuries, nor have they confirmed the precise cause of the blast. The area remained cordoned off as investigators collected evidence and interviewed witnesses. Authorities said the probe will examine whether the fireworks were discharged prematurely or malfunctioned. Further details are expected as the investigation continues.
