DHARAMSHALA September 20: Four Tibetan labourers have been injured after Chinese mining officials opened fire on them over a wage payment clash on Saturday in Tibetan area of Chatreng in Kardze, a newly arrived Tibetan told the Voice of Tibet radio. 

Mining in Chatreng began four years back, the Tibetan said. "Tibetan workers and their Chinese bosses initially had an argument over a wage payment issue," he said. "Later on, the Chinese officials called the police who opened fire on the Tibetan workers."
