(Newshub) – A group of soldiers seek respite from the heat under the shade of a Neem tree. One of them is slumped on a rusty old chair. An AK47 is slung across his chest.Buildings are burnt and broken. The shells of burnt out vehicles line the roadside. We’ve arrived in Malakal in South Sudan’s Upper Nile region. Once one of the country’s major trading centres, it’s now a heavily militarised zone controlled by government forces. Schools have become shelters for the homeless. Food and water is in short supply.
