 I've been in Gaza for nine months and I witnessed some of the most horrific scenes I've seen in the nine months that I've been here. The health facility was overstretched. There were more than 100 people injured. The air was filled with the smell of blood. And one health worker was mopping up pools of blood on the floor using only water because there aren't sufficient supplies of disinfectant material or other cleaning supplies to stop the spread of infections.
