Pakistan Floods - One Year On - Valerie Amos Video Message

A year ago, Pakistan was hit by the worst floods in its history. Nearly 20 million people were affected as flood waters swept across the country.

Valerie Amos traveled to Pakistan in the first few weeks of the crisis, just as she took up her new role as Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator.

"The disaster changed the lives of millions in a matter of days -- causing loss of life and destroying homes," underlined USG Amos. "For those who survived, everyday life became a challenge".
