We held a virtual encounter with Al-Farra and his patients this past Monday via a video call. In the past few weeks, we've sought to document what starvation looks like in Gaza, to witness the gravity of the situation with our own eyes. Israel doesn't allow journalists into the Strip, but via video we've been able to conduct real-time, online tours of hospitals and clinics.

For this article we conducted four such tours, in different places, and conducted separate conversations with another 12 doctors, 10 of them volunteers from the United States and Britain, who are currently in the Gaza Strip or were there recently. What we saw there left no room for doubt about the scale of the horror.
