Trump says any deal with Iran must be 'great and meaningful'

US President Donald Trump said any deal to end the war with Iran must be "great and meaningful", or there will be no agreement at all. Washington and Tehran have downplayed hopes of a breakthrough, despite signs of progress. Iran said the potential agreement focuses on ending the war and the US naval blockade, in exchange for safe transit through the Strait of Hormuz. The proposal, however, will leave out the nuclear issue, which will be negotiated over a 60-day period if the framework accord is agreed on. Kate Fisher reports from Washington DC.
