The boat was on a popular tour of the scenic Ha Long Bay, a UNESCO World Heritage Site with its stunning limestone islands, when disaster struck. Reports indicate that among the deceased are several children, and the search efforts by naval commandos in Quang Ninh Province have continued even after dark to recover bodies and assist survivors. The tragedy marks one of the deadliest maritime accidents in the region in over two decades, prompting Vietnam's Prime Minister to mobilize civil defense resources for the ongoing rescue mission.
