Private American security companies on the ground in Gaza

White House press secretary Karoline Leavitt has made clear that despite his musings about Gaza this week, "the president has not committed to putting boots on the ground in Gaza." But Americans working for private security companies are already operating in the territory. They've been tasked with guarding a strategic area. The World's Shirin Jaafari discusses what these companies do, and how their arrangements with the US work.
