PUNAKHA (AFP) - Bhutans 31-year-old king married a student 10 years his junior on Thursday in a colourful ceremony showcasing the rich Buddhist culture of one of the worlds most remote and insular countries. Amid clouds of incense and chanting monks, the hugely popular King Jigme Khesar Namgyel Wangchuck crowned his queen at the end of a series of rituals in the 17th-century fortified monastery chosen for the occasion. After a brief purification ceremony to start, they walked hand-in-hand and smiling to the inner sanctum of the monastery where an hour of blessings, prostrations and prayers culminated in the queen taking the throne.
