THIMPHU : The tiny Himalayan kingdom of Bhutan on Friday celebrated the birthday of its revered “Dragon King” in a swirl of colourful dances and traditional music. As Jigme Khesar Namgyel Wangchuck turned 34, his subjects - who number fewer than 750,000 - observed a national holiday in the mountainous kingdom, nestled between India and China. In the capital Thimphu, hundreds of well-wishers danced and sang in honour of the Oxford-educated monarch, watched by thousands of spectators in the national dress, which is still required to be worn in schools and the workplace.
