Islamic Relief USA appealed on Tuesday for donations to help thousands of families displaced by fighting between government troops and Taliban militants in Pakistan.
The appeal was part of a campaign to raise 750,000 dollars to some 1.3 million people who need help after being displaced by the fighting in the Swat Valley of Pakistan's North West Province, the organization said in a statement.
It said the intensifying conflict has sent 800,000 fleeing in the last few days alone.
Many of the refugees have settled in government-established emergency camps, where there are shortages of food, clean water and sanitation facilities, the statement said.
"Many of the people who have fled Swat have come to the camps with no more than the clothes they were wearing," said Niyaz Muhammad, an aid worker with Islamic Relief-Pakistan. "They are in urgent need of blankets, clothes and hygiene kits."
Aid workers say many of the children in these camps are suffering from psychological trauma and are at risk of serious health problems.

Islamic Relief said it plans to use the funds it raises to provide support to 11,200 families in camps in Swabi and Marden, focusing mainly on the needs of children.
The funds will be used to obtain blankets, clothing, cooking sets and clean water and provide psychological support for the children, according to the statement.
Islamic Relief is represented in 35 countries and has been working in Pakistan since 1992.
