Tourist safety in Vietnam's famed bay questioned - Article Photos 2/4

FILE - In this Feb. 18, 2011 file photo, a tour boat, submerged in the water, is pulled up in the Halong Bay in northern Quang Ninh province, Vietnam, a day after 12 people from nine nations died when their boat sank early in the morning. Each day, up to 10,000 tourists from around the world sail around the bay, a UNESCO-heritage site and one of the country's most visited tourist attractions, and gaze at its stunning limestone pillars and caves. But at least four deadly accidents over the last 10 years and many more alarming safety incidents recounted on traveler’s blogs have led to allegations that the ships are cutting corners.
