A New Year massacre in Istanbul - at least 39 are killed and dozens hurt in a nightclub terror attack. The gunman, who was wearing a Santa Claus costume, is still at large. The slaughter came just hours after the UN Security Council unanimously approved a resolution, drafted by Turkey and Russia - endorsing a nationwide ceasefire in Syria. And, among the week's top stories, the Obama administration slaps new sanctions on Russia over alleged meddling in the U.S. election - but Moscow refrains from tit-for-tat measures.
