Iran says it will retaliate if President Trump carries out his threat to hold the country accountable for the actions of the Houthi group in Yemen. The Houthis - who are backed by Iran - have been targeting shipping in the Red Sea in solidarity with Gaza. Mr Trump issued his threat as US forces launched massive air strikes against Houthi targets, killing more than thirty people. We speak to a Houthi official.
