One of the largest graveyards in the world is now a camp for hundreds of Pakistanis.

Although this graveyard in the southern Sindh province is a historical site-- where some 125,000 Sufi saints are said to have been buried-- flood victims are more concerned with what they lost than the history surrounding them.

"We have suffered great losses. We could hardly pick up our clothes. Our belongings and grain, all were left behind."

Torrential rains have triggered Pakistan's worst natural disaster on record, forcing more than six million people from their homes.

In the Punjab province, some people held onto their homes despite efforts by officials to persuade them to flee to safety.

Now they are stranded in dry pockets in the flooded region.

Relief rations from military personnel in rescue boats are not enough.

"There is no way out of here. We can't go anywhere. We are just marooned here, with no food. No one is coming to help us. We are hungry. We have women and children and there is no medicine for them."

The disaster has killed more than 1,600 people and inflicted billions of dollars of damage to homes, infrastructure and agriculture.

It has also stirred anger against the U.S.-backed government that has struggled to cope with the catastrophe.
