On June 8, 2024, Israel initiated a military action that rescued 4 hostages and killed 274 Palestinians (mostly civilians), according to Gaza Health Authorities. While the United States acknowledged assisting Israel in the operation, it denied that the floating pier was used.[10] A video emerged on social media showing an Israeli Black Hawk helicopter close to the pier picking up IDF soldiers and hostages.[104] The video also shows military equipment, including a US counter-drone system, on the pier.[10]

The Popular Resistance Committees in Gaza released a statement in which it "confirms the participation of American enemy forces stationed on the floating dock" to conduct an attack on the Nuseira refugee camp.[11] Euro-Med Human Rights Monitor said IDF didn't just evacuate using the pier and that it was likely that the IDF entered into Gaza using the pier as well.[105] United States officials told CBS News reporters that the video appearing to show the helicopter taking off from the beach near the pier, showed the helicopter landing south of the facility and not within the cordoned off area adjacent to pier.[104]

Shortly after the rescue operation, it was announced that the United Nations World Food Program would pause all of its work with the pier, until a security review and review of how the IDF may have utilized the pier was completed. During the review, undistributed humanitarian aid remained on the beach, as the UN worked to transfer it to warehouses and local aid teams within Gaza.[106]

Saying "never" for delivering aid was not entirely correct. Apparently it delivered two days of aid worth in over three months accorsung to the US military. However iirc. there was issues with the aid being delivered on land and then blocked from actual distribution by Israel. One of the key groups destined to distribute the aid, Woeld Central Kitchen had one of their clearly markes and coordinated convoy bombed repeatedly by Israel, murdering 7 humanitarian workers.

The Financial Times estimated less than 600 trucks of aid were delivered via the pier, about two days of aid to Gaza before the war, calling the pier a "colossal failure".[112]

At a press conference on July 11, US President Biden said he was disappointed with the failures in providing aid through the Gaza floating pier.[113]
