Gordon Robison: US correspondent on the US launching new strikes on Iran

Hostilities have ignited again between Iran and the US, undermining the fragile memorandum of understanding.  US Central Command claims it's bombed more than 80 Iranian targets - the vast majority being small boats in the Strait of Hormuz.  It says this is retaliation for Iran attacking three commercial vessels in the waterway. Middle East correspondent Gordon Robison says it's not clear why the ships were hit - but there's been a noticeable back and forth between both nations, leaving the ceasefire on 'life support'.
