The authorities in Tibet have given anti-Chinese demonstrators until Monday to surrender, following violence that officials say left 10 people dead. “The plot of the separatists will fail,” the head of Tibet’s government warned as security forces patrolled the main city, Lhasa.

State media said the 10 killed in Friday’s clashes had included business people who were “burnt to death”.

But exiled Tibetan leaders put the death toll higher and blamed China.

“There have been 30 confirmed deaths until today, and over 100 unconfirmed deaths,” the Tibetan government in exile, which is based in northern India, said.
