Washington: The US military's problem-plagued mission to deliver desperately needed aid to Gaza via a temporary pier has ended, a senior American officer said Wednesday.

US President Joe Biden has expressed disappointment in the performance of the pier, which has repeatedly been detached from the shore because of bad weather since its initial installation in mid-May, limiting the time it has been operational.

"The maritime surge mission involving the pier is complete, so there's no more need to use the pier," Vice Admiral Brad Cooper told journalists.

The pier was damaged by bad weather in May and had to be removed for repairs. It was then reattached on June 7, but was moved to Ashdod on June 14 to protect it from anticipated high seas - a situation that was repeated later in the month.

Distribution of aid once it reaches land has also been a problem, with the UN World Food Programme suspending deliveries of assistance that arrived via the pier last month to assess the security situation after Israel conducted a military operation nearby.

Biden announced the pier project during his State of the Union address in March as Israel held up deliveries of assistance by land, and the Pentagon has said it helped push the Israeli government to open more aid routes.

"The deployment of this pier has... helped secure Israeli commitment to opening additional crossings into northern Gaza," Deputy Pentagon Press Secretary Sabrina Singh told journalists last week.
