Photos of the Dalai Lama and other senior religious leaders at Kirti monastery in Ngaba county, Ngaba Tibetan Autonomous Prefecture, Sichuan province, were damaged following a raid on the monastery in early April 2008. Kirti monastery was at the center of the wave of protests in eastern Tibet when monks were joined by laypeople and schoolchildren in a major protest on March 16, 2008, calling for a free Tibet, with pictures of the Dalai Lama and Tibetan flags on display.
