Crowds of desperate people in the Gaza Strip have intercepted almost all of the aid sent over a temporary pier built by the U.S. military, officials said, forcing a temporary halt to deliveries and complicating an already dire humanitarian crisis.

In a briefing on Tuesday, Pentagon spokesperson Pat Ryder said that 569 metric tons of aid has been brought in via the pier, which cost about $320 million to build and operate, for delivery onward.

But asked if any had made it through to aid groups for distribution, he responded, "As of today, I do not believe so.”
