WASHINGTON (AP) — Trucks carrying badly needed aid for the Gaza Strip have rolled across a newly built U.S. pier and into the besieged enclave for the first time. Friday’s shipment is the first in an operation that American military officials anticipate could scale up to 150 truckloads a day. It comes as Israeli restrictions on border crossings and heavy fighting hindered the delivery of food and other supplies seven months into the Israel-Hamas war. But the U.S. and aid groups warn that the floating pier project is not a substitute for land deliveries that could bring in all the food, water and fuel needed in Gaza. Before the war, more than 500 truckloads entered the territory on an average day.
