Pakistan's disaster relief agency estimates that weeks of monsoon flooding have killed 455 people and affected more than five million others.

Officials said every section of the country has been affected over the past five weeks.

The worst hit area has been the lowlands of Sindh province, which lies along the coast. The province accounts for more than half of the flood-related deaths and nearly all of the more than a quarter of a million people in relief camps.

In terms of agriculture, Punjab province has suffered the most damage with almost a half million acres of crops affected. The southwestern province of Baluchistan suffered the most loss to livestock, with nearly 7,000 cattle killed.

Pakistan is no stranger to seasonal flooding. The country has suffered devastating floods in the past two years, including the worst in nearly a century, which happened in 2010.

That disaster submerged an area the size of England, killed almost 1,800 people and affected some 21 million others.
