In North Korea, Kim Jong-un has lead celebrations to mark the birthday of his father, Kim Jong-il, who died just over a year ago.

Earlier this week North Korea conducted a third nuclear test, claiming to have successfully detonated its biggest device yet - a move instantly condemned by the UN Security Council.
