Palestinians in Gaza are reacting to a possible shift in the world's attention away from the Israel-Hamas ceasefire to a new regional conflict with Iran. Israel closed all crossings into the territory of over 2 million people in the wake of its new strikes on Tehran. The Israeli military body overseeing civilian affairs in Gaza said it closed the crossings because they cannot not be safely operated under fire. It said crossings would reopen as soon as the security situation allows. Palestinians fear new lack of access to food and other basic necessities from the outside world. Memories of hunger during last year's Israeli blockade remain fresh. The latest conflict comes days after U.S. President Donald Trump rallied billions of dollars in pledges for Gaza’s reconstruction.
