A pro-Tibet activist attends a demonstration in Warsaw March 10, 2009 to mark the 50th anniversary of the Tibetan uprising against China. The Dalai Lama marked 50 years in exile on Tuesday by demanding "meaningful autonomy" for his Tibetan homeland, where Chinese authorities tightened security to stifle protests against their rule.
