Iran has made 'a very bad mistake' says President Trump

President Trump has said he finds it hard to believe that Iran would have deliberately shot down an American surveillance drone. The Pentagon says the attack happened in international airspace, contradicting Tehran's claim that the unmanned aircraft was over its territory. We hear from a former general in the US army. We also hear from Saudi Arabia's deputy foreign minister.

Also coming up President Xi Jinping is making his first visit to North Korea for 15 years. What does North Korea hope to obtain from him? And what does China expect in return? And we hear the song of the North Pacific Right Whale, one of the rarest whales on the planet, whose song has been recorded for the first time ever.
