HANOI, Vietnam (AP) — Heavy rain and strong winds from the former Typhoon Bualoi flooded roads, knocked off roofs and caused at least 12 deaths in central Vietnam before weakening to a tropical storm that moved Monday into Laos, state media reported. The storm tore through communities, damaging houses, schools and power poles, sweeping away temporary bridges and flooding roads and low-water crossings across several provinces. Nine of the deaths occurred in the scenic province of Ninh Binh, where strong winds collapsed houses. In Quang Tri province, strong winds broke the ropes anchoring a fishing boat taking shelter, sending nine crew members and the vessel adrift. State media said more than 347,000 households lost power before the typhoon made landfall just after midnight on Sunday.
