Sweeping UN economic and military sanctions have been reimposed on Iran - 10 years after they were lifted in a landmark international deal over its nuclear program.

The new measures took effect as the three European partners to the deal - the UK, France and Germany - activated the so-called "snapback" mechanism, accusing Iran of "continued nuclear escalation" and lack of co-operation.

Iran suspended inspections of its nuclear facilities - a legal obligation under the terms of the 2015 deal - after Israel and the US bombed several of its nuclear sites and military bases in June.

KAN's Mark Weiss spoke with Dr Avi Davidi, a senior Iran expert at the JISS, the Jerusalem Institute for Strategy and Security.
