DEIR AL-BALAH, Gaza Strip — A U.S. Army vessel carrying equipment to build a temporary pier in Gaza was heading to the Mediterranean on Sunday, after U.S. President Joe Biden announced plans to increase aid deliveries by sea to the besieged enclave where hundreds of thousands of Palestinians are going hungry.

The new push for aid came as the Muslim holy month of Ramadan was set to begin Monday in much of the world after officials in Saudi Arabia saw the crescent moon. Hopes for a new cease-fire by Ramadan faded days ago with negotiations apparently stalled.

The opening of the sea corridor, along with airdrops by the U.S., Jordan and others, reflected growing alarm over Gaza’s deadly humanitarian crisis and a new willingness to bypass Israeli control over land shipments. But aid officials say that air and sea deliveries can’t make up for a shortage of land routes. Aid trucks entering Gaza daily are far below the 500 entering before the war.

A ship belonging to Spanish aid group Open Arms and carrying 200 tons of food aid was expected to make a pilot voyage to Gaza from nearby Cyprus “as soon as possible,” but not Sunday, said Linda Roth, a spokesperson for partner organization World Central Kitchen. There was no explanation after Cyprus’ president had said it would leave then.

Israel says it welcomes the sea deliveries and would inspect Gaza-bound cargo before it leaves Cyprus. Israeli Defense Minister Yoav Gallant reviewed preparatory work off Gaza's coast on Sunday.

PORT-AU-PRINCE, Haiti — The U.S. military said Sunday that it had flown in forces to beef up security at the U.S. Embassy in Haiti and allow nonessential personnel to leave.

The aircraft flew to the embassy compound, the U.S. Southern Command said, meaning that the effort involved helicopters. It was careful to point out that “no Haitians were on board the military aircraft.” That seemed aimed at quashing any speculation that senior government officials might be leaving as the gang attacks in Haiti worsen.

The neighborhood around the embassy in the capital, Port-au-Prince, is largely controlled by gangs.

“This airlift of personnel into and out of the Embassy is consistent with our standard practice for Embassy security augmentation worldwide, and no Haitians were on board the military aircraft,” according to the Southcom statement.

In many cases, nonessential personnel can include the families of diplomats, but the embassy had already ordered departure for nonessential staff and all family members in July. The personnel ferried out of the embassy may have simply been rotating out, to be refreshed by new staff.
