When covering Ethiopia's civil war in 2021, we reported extensively on a siege which saw the Ethiopian government seal off Tigray, a region of 6 million from the outside world and cut off food, medical supplies, phone/internet for over a year...with the goal of flushing out rebel fighters based there. It led to scores of deaths from famine & treatable illnesses.
It's why reports of a siege on Gaza horrify me. A humanitarian siege guarantees industrial scale suffering.
