As Israel continues its full-fledged military ground invasion of Gaza City, Democracy Now! speaks with Kathleen Gallagher, a U.S. military veteran and general surgeon currently volunteering in Gaza, who describes the scene on the ground from Nasser Hospital in Khan Younis. Gallagher says she sees up to 400 patients a day, about 40% of whom are under the age of 20. This week she reports seeing six children killed with gunshot wounds to the head. After volunteering in Honduras and Ukraine, “This is worse than anything I’ve ever seen,” Gallagher says.
