The United States says its relief helicopters are now supplying twice as much aid to key distribution centers in quake-ravaged areas of Pakistan.
The U.S. Embassy in Islamabad said Sunday this is to ensure at least a 30-day food supply in remote villages before bad weather grounds flights again.
The statement says U.S. Chinook helicopters are now delivering over 100 tons of cargo a day, doubling their usual load by hanging supplies in nets under the aircraft.
Meanwhile, the United Nations and Pakistani authorities are investigating why Pakistani earthquake victims forced their way onto two aid helicopters Friday and made the pilots airlift them from the disaster zone.
The October 8 quake killed more than 73,000 people and made more than three million people homeless.
