The US is sending an additional $800 million in heavy artillery weapons, ammunition and tactical drones to help those on the “frontlines of freedom”, as President Joe Biden puts it. It comes as Russian President Vladimir Putin ordered his troops not to storm the steel plant where the last group of Ukrainian fighters in Mariupol is holding out. Instead, he’s told them to seal it up so that not even a “fly” could escape. Meanwhile, the consequences of the war go beyond Ukraine, with the world facing a “human catastrophe” from a food crisis, according to World Bank boss David Malpass. Ukraine is a big producer of wheat, maise, sunflower oil, and fertiliser. Prices have risen sharply across the world following Russia’s invasion- the United Nations says they are at their highest since records began 60 years ago. If the crisis continues, Malpass says hundreds of millions of people will be pushed into poverty and hunger.
