State-run China Central Television on Wednesday began the first of what are billed as elaborate and technically difficult live broadcasts from Everest's base camp for the torch's journey up the world's tallest peak. Mountaineers were completing the setup of a staging point at 8,300 meters (27,390 feet) for the final assault on the 8,850-meter (29,035-foot) summit, CCTV reported.

Yet there was no word on the location of the torch, which mountaineers on the 31-member climbing team would go to the summit, their whereabouts and when they would scale the peak. The Web site of Beijing Daily likened the lack of information to a "mysterious veil that has surrounded base camp."

Some media reports had speculated that the climb could come as early as Wednesday - the 100-day countdown to the August 8-24 games - or Thursday - the May Day holiday. A brewing storm made a climb in the next three days unlikely, the Xinhua News Agency cited Yang Xingguo, the expedition's weather expert at base camp, as saying late Wednesday.

Still billed as a spectacular event in the buildup to the August games, the Everest climb is being given mixed treatment. With the torch relay dogged by protests worldwide and Beijing's oft-criticized rule in Tibet drawing heated scrutiny after widespread anti-Chinese protests this spring, organizers have placed a premium on security.

The Everest torch, specially designed to burn in frigid, windy, oxygen-thin Himalayan air, is a sister flame to the one that made its way around the world and Wednesday reached Hong Kong, returning to Chinese territory after a month abroad. Organizers did not publicize the Everest flame's travel to base camp over the past month, apparently to avoid protests.

Beijing has also exercised its diplomatic clout, persuading neighboring Nepal to bar climbers from border-straddling Everest's southern face to keep potential protesters from reaching the peak and spoiling the torch's moment.

But the secrecy has also dented plans by organizers and CCTV, which spent heavily on special broadcast facilities, to promote a torch run that is physically challenging but that has been criticized by Tibetan activists as a symbol of Chinese domination of Tibet.
