Arkansas flash floods hit campsites and leave 20 dead

At least 20 people have died in the US state of Arkansas after flash floods hit campsites in a mountainous national park, state governor Mike Beebe says.
A rescue operation has been launched and emergency workers say more than three dozen people are unaccounted for.
Two helicopters are taking part in the search, in a remote, mountainous area in the state's south-west.
The search operation is focused on campsites along the Little Missouri and Caddo rivers.
The remains of destroyed tents and damaged log cabins lined the banks of the swollen rivers on Friday.
A river gauge at Langley, just south of Albert Pike in the Ouachita National Forest, showed the water rose 8ft (2.4m) in one hour, according to the US Geological Survey.
The National Weather Service said 7.6in (19.3cm) of rain had fallen overnight. 'People trapped'
Police spokesman Bill Sadler told US network CNN: "We believe there are still individuals trapped in the area.
"The primary mission of the Arkansas state police working with the local authorities right now is to get the living out of that area and locate the dead."
Officials were bringing in a refrigerated truck to act as a temporary morgue, he said.
Police originally put the death toll at 12 but later updated it to 20.
It is not clear whether all those killed were staying at the campsites washed away by the flash floods.
Brigette Williams, of the American Red Cross in the state capital Little Rock, said between 200 and 300 people were believed to be in the area at the time but it was unclear how many were campers and how many local residents.
Rescue worker Gary Fox said the Albert Pike Recreation Area, a 54-unit campsite in the national forest, was packed with families on holiday when the flash flood hit.
More than 20 people were taken to hospital and another 60 were rescued from the steep Ouachita Mountains valley.
The region includes a mix of campsites, hunting grounds and private homes.
Marc and Stacy McNeil of Marshall, Texas, survived by hauling their pick-up truck between two trees and standing in waist-deep water.
"It was just like a boat tied to a tree," Mr McNeil said, describing how the truck bobbed up and down.
They said the water kept rising throughout the night. By dawn the rain stopped, the water receded and they were able to walk to safety.
National Guard troops are helping to look for those affected.
Mr Beebe said the deaths had occurred at about 0530, when the floodwaters reached their peak.
