Sanawan, Pakistan: A Pakistani woman stranded by the country's worst floods in 80 years gave birth to twin boys on Monday, bringing joy to soldiers and villagers struggling amidst death and destruction.

The floods have killed 1,600 people and affected more than 13 million.

Amry helicopter pilot Captain Abdul Munim Khan thought he was picking up another dead victim of the deluge when he landed in a flooded village and men bearing a body on a rope bed, covered by a sheet, moved towards him through chest-deep water.

"But when they came close, I realised that she was alive. To my pleasant surprise, there were also the twin boys," Khan told Reuters after the rescue.

The young mother, Zahida Perveen, who gave birth in the open, was taken to hospital with her boys.

"I was so happy, I was weeping when I saw they were boys," Perveen said from her hospital bed.

Mother and children were doing fine, hospital officials said.
