The UN warned Friday of soaring human rights violations in Sudan's Darfur region and said they were "verging on pure evil," amid escalating fighting seven months into the war between the army and paramilitaries. "We keep saying that the situation is horrific and grim. But frankly, we are running out of words to describe the horror of what is happening in Sudan," said Clementine Nkweta-Salami, the UN humanitarian coordinator for Sudan. "What is happening is verging on pure evil," she said.
