Live update: International delegations speaking during annual Iran Freedom rally in Paris
20: 12 (GMT+1) : General George Casey, former Commander of the Multi-National Force Iraq (2004-2007) and Chief of Staff of the US Army until 2011, says: "Iran has a destabilizing role in the region, which I have personal experience with. It is by now beyond dispute that the regime in Tehran is fomenting instability and conflict throughout the region, most notably in Syria, Lebanon and Iraq.
