US submarine torpedoes Iranian warship

Iran has carried out further attacks on several different countries as Israel and the United States continue to strike Iranian targets. We get analysis of the US torpedoing of an Iranian warship from former First Sea Lord, Admiral Lord West. We also hear from Iranians leaving the country and from inside Tehran. Plus, we put listeners questions about the war to our Chief International correspondent Lyse Doucet, and defence expert Karin Von Hippel.
