Ms Steenkamp, 47, and her husband, both Afrikaners, were commercial farmers but said they had lost their land recently after it was invaded by people who "took over the whole farm" just as they were about to sell it in order to "downscale".

Far from Gaza, in London, I talked to Philippe Lazzarini, the commissioner-general of Unrwa, the UN agency that supports Palestinian refugees. He told me that he was running out of words "to describe the misery and the tragedy affecting the people in Gaza. They have been now more than two months without any aid"."Starvation is spreading, people are exhausted, people are hungry... we can expect that in the coming weeks if no aid is coming in, that people will not die because of the bombardment, but they will die because of the lack of food. This is the weaponisation of humanitarian aid."

If words are not enough, look at the most authoritative data-driven assessment of famine and food emergencies in the regular reports issued by Integrated Food Security Phase Classification, or IPC. It is a joint venture by UN agencies, aid groups and governments that measures whether a famine is happening.The latest IPC update says Gaza is close to famine. But it says that the entire population, more than two million people, almost half of whom are children, is experiencing acute food insecurity. In plain English, that means they are being starved by Israel's blockade.The IPC says that 470,000 Gazans, 22% of the population, are in a classification it calls "Phase 5 – catastrophe." The IPC defines it as a condition in which "at least one in five households experience an extreme lack of food and face starvation resulting in destitution, extremely critical levels of acute malnutrition and death."

In practical terms, the phase five classification, the most acute used by the IPC, estimates that "71,000 children and more than 17,000 mothers will need urgent treatment for acute malnutrition".Thousands of tons of the food, medical aid and humanitarian supplies that they need are sitting only a few miles away, on the other side of the border in Egypt.

In London I asked Mr Lazzarini whether he agreed with those who have accused Israel of denying food and humanitarian aid to civilians as a weapon of war.

"I have absolutely no doubt," he said, "that this is what we have witnessed during this last 19 months, especially during this last two months. That's a war crime. The quantification will come from the ICJ [International Court of Justice] not from me, but what I can say, what we see, what we observe, food and humanitarian assistance is indeed being used to meet the political or military objective in the context of Gaza."Some enthusiasts launched

, a project to recruit a group of volunteer photographers around the world and get them accreditation to attend film festivals, conferences and other events."Wikipedia has for the longest time had missing or poor quality photos of people," said Kevin Payravi, one of the project's founders.

"This issue has always been in the back of our minds as Wikipedia editors."He spoke to the BBC from Austin, Texas where he and fellow founder Jennifer 8. Lee were covering the SXSW festival, complete with their own photo booth for set-up portraits.
