At least ten young children from the group of Tibetans who came under fire near the Tibetan border with Nepal on September 30 have been taken into Chinese custody, according to new eyewitness accounts from climbers on Mount Cho Oyu at the time. A British climber and several other witnesses, speaking on the phone from Nepal, described a tense and 'intimidating' atmosphere following the shooting as the armed security personnel 'took over' advance base camp at Cho Oyu, which is approximately 20 km west of Mount Everest at the border between Tibet and Nepal. Additional reports from the Nangpa Pass area, which is at around 19,000 feet, indicate a stepping up of border security following the incident, with increased movements of troops towards the Tibetan border town of Tingri in the past 24 hours.
