Rain halts all quake relief helicopter flights in Pakistan
"All helicopter flights have been stopped from Chaklala," the official said.
"There are dozens of helicopters and choppers with relief goods but they are stranded at the base for the past one hour. They cannot fly until weather is clear here and up in the north and Kashmir."
Pakistan Air Force spokesman Air Commodore Sarfraz Khan said the weather conditions had also stranded helicopters in the northern regions hit by the quake.
"Some are stranded at Chaklala, some are stranded in the northern areas," he said.
The choppers have been a vital part of the effort to reach remote areas of Pakistan cut off when landslides wiped out many roads. The main roads to Muzaffarabad were reopened earlier today.
