In the past five days, the nongovernmental organization received between $40,000 and $50,000 in donations, which will help 550 families in Gaza who need food and shelter because of the conflict, Zaru said. Donors include Jewish-Americans and people in Asia, he said.

"Some of their houses have been bombed and it's going to be a while before they can get back to them," Zaru said of the Gaza families. "We're dealing with this on a day-by-day basis."
