Mr. Singh, who flew over Krishna and Guntur districts on Friday, saw the damage caused by the floods while flying over Mahabubnagar and Kurnool. He later left for an aerial visit of the flood-hit parts of neighbouring Karnataka.

Andhra Pradesh Chief Minister K. Rosaiah, Karnataka Chief Minister B.S. Yeddyurappa and Union Minister M. Veerappa Moily accompanied the Prime Minister.

Mr. Singh had on Friday announced Rs.1,000 crore as advance assistance for Andhra Pradesh for relief and rehabilitation. He also assured that more aid would be provided and that money would not be a constraint for relief and rehabilitation works.
