A senior Chinese official has ordered tighter security in Tibetan Buddhist monasteries and on main roads following deadly protests in Sichuan province, the BBC said. Lhasa Communist Party Secretary Qi Zhala also warned of a crackdown on those involved in “separatist, destructive and criminal” activities. The move came after protesters clashed with security forces in parts of Sichuan province last week. At least three people are reported to have died, with dozens more injured.
