A Russian Defence Ministry plane bound for Syria has gone missing - disappearing from radar screens just minutes after departing from the Russian city of Sochi. A major search operation is currently underway. We spoke exclusively to a Russian army choir singer, who was supposed to be on the doomed plane - but asked not to go at the last moment, after the birth of his son. And - stories that have shaped the week. A deadly terror attack on a German Christmas market - as a truck ploughs into a crowd of people, killing 12 and injuring dozens more. The Russian ambassador to Turkey is gunned down in cold blood in Ankara - by a former local policemen, shouting, "Don't forget about Syria!" Terror group al-Nusra says it masterminded the killing.
