A Tibetan activist unfurled a Tibetan flag and then set himself on fire today outside the Mumbai hotel where Chinese President Hu Jintao was courting Indian business leaders eager to boost trade between Asia’s emerging giants.

Thousands of Tibetans living in India offered a special prayer today for the 70th birthday of their exiled spiritual leader, the Dalai Lama, who said he was striving toward happiness as he marked the day.
