JERUSALEM (AP) Humanitarian workers have started moving tons of aid that piled up at a U.S.-built pier off the Gaza coast to warehouses in the besieged Palestinian territory, the United Nations said Saturday, an important step as Washington considers whether to resume pier operations after yet another pause because of heavy seas.

It wasnt known when the aid might reach Palestinians in Gaza, where experts have warned of the high risk of famine as the Israel-Hamas war is in its ninth month. This is the first time trucks have moved aid from the pier since the World Food Program, a U.N. agency, suspended operations there because of security concerns on June 9.

In just the last week, more than 10 million pounds were moved ashore, according to the U.S. military.

WFP spokesperson Abeer Etefa told The Associated Press this is a one-time operation until the beach is cleared of the aid and is being done to avoid spoilage. Further U.N. operations at the pier depend on security assessments, Etefa said. The U.N. is investigating whether the pier was used in an Israeli military operation last month to rescue three hostages in a raid that killed more than 270 Palestinians .

If WFP trucks successfully bring the aid to warehouses inside Gaza, that could affect the U.S. militarys decision on whether to reinstall the pier, which was removed because of adverse weather on Friday. U.S. officials said they were considering not reinstalling it because of the possibility that the aid would not be picked up.

Lawlessness around humanitarian convoys is another challenge to aid distribution. The convoys have come under attack in Gaza. While most aid deliveries come by land, restrictions around border crossings and on what items can enter Gaza have further hurt a population that was already dependent on humanitarian aid before the war.
