“President Barack Obama has defended the use of drones in a ‘just war’ of self-defence against deadly militants and a campaign that had made America safer. In a wide-ranging speech on a programme shrouded in secrecy, he said there must be ‘near certainty’ that no civilians would die in such strikes. In a renewed push to shut Guantanamo Bay, he said he had lifted a moratorium on prisoner transfers to Yemen. Mr Obama also defended the use of drones to kill four US citizens.”
