Tibetans in Lhasa observing Ganden Ngamchoe, an annual religious festival held to commemorate the death of the founder of the Gelukpa school of Tibetan Buddhism, Je Tsongkhapa, were kept under heavy surveillance by Chinese police forces during the celebrations. Two short video clips from Tsuglakhang and Barkhor areas showed police officers lining the streets and keeping close watch on Tibetans circumambulating holy sites. A police drone was also in attendance.
