It wasn't known when the aid might reach Palestinians in Gaza, where experts have warned of the high risk of famine as the Israeli 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 release three captives 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. military’s 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.

While most aid deliveries come by land, Israeli 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.
