Prince Naif, who is supervisor of King Abdullah Relief Program for Pakistan, said greater humanitarian and relief efforts were required to save the lives of millions of people affected by the flood. Saudi Arabia has already sent several planeloads and truckloads of relief supplies to the affected areas in Pakistan.

Custodian of the Two Holy Mosques King Abdullah had earlier ordered a nationwide fundraiser that collected more than SR400 million.

King Abdullah also ordered that 1,000 truckloads of relief supplies be distributed among the flood victims. During the two-month-long relief program, trucks will carry foodstuffs such as rice, flour, cooking oil and milk, beans and lentils.

Saudi Arabia has established two field hospitals near the flood-hit areas to provide health services. It also sent a team of Civil Defense officers to take part in search and rescue operations.

The floods are Pakistan's worst-ever natural disaster in terms of the amount of damage and the number of people affected, with more than six million people forced from their homes, about a million of them in the last few days as the water flows south.

The disaster has killed about 1,600 people, inflicted billions of dollars in damage to homes, infrastructure and the vital agriculture sector.
