There are more than 1,000 journalists working inside Gaza, the International Federation of Journalists estimates. Like nearly all of Gaza’s two million residents, most have slept in tents or the courtyards of hospitals or in their cars. Some have had dozens of relatives killed. Some have isolated themselves from their children because they fear being targeted as journalists. Movement within Gaza is challenging. Israel does not allow people to cross between north and south. Journalists — like all civilians — struggle to keep up with neighborhood evacuation orders, strike warnings and the routes of aid convoys that frequently erupt in riots. Editors weigh the relative risks of every assignment, often employing security experts to help make the call. When messages go unanswered for hours — or days — everyone worries. The recent spate of killings has had a chilling effect. “It’s reached the point where I’m scared to report,” one photographer told The Times. Another, who was wounded along with his daughter during a July strike on a nearby home, said: “There’s a lot of fear, and there’s no protection.” Israeli officials have argued that all Gazan reporters are inherently biased. But in contrast to the Israel-Hamas wars that I covered in 2012 and 2014, international correspondents are not allowed to enter Gaza except under military escort. That makes it extremely difficult to report independently. Without Gazan journalists, “there’s no other source of information from Gaza other than Hamas itself,” said Dan Perry, a longtime A.P. bureau chief in the region.
