LONDON — Britain's Prince William is celebrating his 28th birthday in training with the country's Royal Air Force.

The second-in-line to the British throne returned Sunday from a visit to charities in Botswana and Lesotho, and a trip to watch England's soccer team Friday at South Africa's World Cup with younger brother Prince Harry.

William is training to become an RAF search and rescue helicopter pilot, part of his preparations to one day succeed Queen Elizabeth II and his father, Prince Charles — heir to the throne, as the British monarch.

Royal watchers will look for hints that William's birthday today could prompt an engagement to longtime girlfriend Kate Middleton.

HANOI, Vietnam — Vietnamese legislators rejected a proposed bullet train over its $56 billion cost — the assembly's first rejection of a major proposal submitted by the all-powerful Communist government.The nearly 500-member assembly typically acts as a rubber stamp but voted over the weekend to deny plans for the high-speed rail project.The $56 billion investment would have built a 975-mile track linking the capital Hanoi and the southern commercial hub of Ho Chi Minh City by 2035.A train trip that now takes 30 hours would have been cut to about six hours.But ordinary Vietnamese could not afford the fares, and construction would equal about 50 percent of the country's gross domestic product, said Nguyen Minh Thuyet, a lawmaker from northern Lang Son province.
