The tour operator said he was as yet unaware of the consequences but air services were at the ready. "I cannot comment on their condition at this stage, but a helicopter is being arranged," he said. "Volunteers from the area are being dispatched there."
The names of the Italian climbers involved are Tarcisio Bello, who was the crew's leader, Luca Morellato, David Bergamin and Tino Toldo.
According to Karrar Haidri, secretary of the Pakistan Alpine Club, authorities were trying to send a helicopter to Ghizar, which is home to the landscapes of the Phander Valley, in an effort to rescue the climbers and return them safely back to the base camp.
"A rescue mission will begin tomorrow (Tuesday) and we are praying for the safety of stranded mountaineers," he told The Associated Press.
In March this year, two climbers perished as they were ascending the Pakistani mountain of Nanga Parbat.
