A United Nations agency says it suspended an aid program for Gaza residents displaced in last summer's Israel-Hamas war because of a large shortfall in funds from donor countries.

The U.N. Relief and Works Agency said Tuesday it helped 66,000 families repair homes or rent shelters, but that it has run out of money to help more.

The agency assists refugees and their descendants from the 1948 and 1967 Mideast wars — a majority of Gaza's 1.8 million people.

The international community pledged $5.4 billion in aid to Gaza following the 50-day war in which tens of thousands of homes were damaged or destroyed.

Robert Turner, head of the U.N. agency in Gaza, says that "virtually none" of that money has reached Gaza and that this is "distressing and unacceptable."
