BBC director general Tim Davie said: "Across the BBC, we are all incredibly sad to hear the news about George. We are thinking of his family at this time.<br /><br />"George was one of the best and bravest journalists of his generation who reported fearlessly from across the world as well as presenting the news flawlessly.<br /><br />"He was more than just an outstanding journalist, audiences could sense his kindness, empathy and wonderful humanity. He was loved by all and we will miss him enormously."
