(The Guardian) – Attacks against civilians in war zones across the world have grown more indiscriminate due to a myopic focus by the major global powers on fighting terrorism, the head of the international charity Médecins Sans Frontières has said. In an interview with the Guardian, Joanne Liu, the Canadian physician and president of MSF, issued a broad indictment of how modern warfare is conducted, declaring that world powers have failed in their duty to uphold the rules of conflict, threatening a return to “barbarian times”.
