A boat returning from an island trip in southern Vietnam capsized on Saturday, killing 15 Indian tourists less than half a kilometre (0.30 mile) from shore, as passengers shouted for help, officials and a witness said. The speedboat was carrying 32 Indian tourists and four crew members when it overturned on Saturday afternoon shortly after leaving Hon May Rut Ngoai Island, which is near Phu Quoc, Vietnam’s largest island, authorities were quoted as saying.
