Calling himself a "simple Buddhist monk" who usually didn't celebrate birthdays, the Dalai Lama marked his 90th on Sunday by praying for peace after China insisted it would have final say on who succeeded the Tibetan spiritual leader.

Thousands of people gathered in India’s Dharamshala on Sunday to celebrate the 90th birthday of the Dalai Lama – a key milestone in the life of the spiritual leader and Nobel Peace laureate known for his message of compassion and his quest for greater freedoms for Tibet under Beijing’s rule.

Thousands of followers from around the world, including celebrities and officials from the United States and India, will attend the birthday celebrations in Dharamshala.
