The US is sending helicopters, boats, bridges and other supplies to flood-hit Pakistan as part of an initial $10 million aid pledge, a media report said.
"Our thoughts and prayers are with all those who have lost loved ones or have been displaced from their homes - and we are taking action to help," Geo TV reported quoting US Secretary of State Hillary Clinton on Sunday.
"Our embassy in Islamabad is coordinating closely with Pakistani authorities to support rescue and relief efforts.
"And we will work closely with the government of Pakistan to ensure aid reaches those people who need it most. I have seen first-hand the strength and resilience of the Pakistani people and I know they will come through this tragedy with determination and compassion," she said in a statement.
At least 1,300 people have been killed in floods in Khyber-Pakhtunkhwa province and over 1.5 million people have been affected.
