Fighting continues across Ukraine

Fighting is continuing across much of Ukraine. A resident of the southern city of Mariupol tells us the Russian attacks have been indiscriminate.

Also, we discuss how real President Putin's threat of a nuclear response is.

Joining Paul Henley to discuss these and other issues are Nathalie Tocci, director of the Institute of International Affairs in Rome. She's also Special Advisor to EU High Representative and Vice President of the Commission, Josep Borrell; and Andri Snaer Magnason, an Icelandic writer and documentary film-maker.
