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 programme. Talks between the three countries and Iran on the sidelines of the UN General Assembly earlier this week failed to produce a deal which would have delayed the sanctions being reimposed. Iran stepped up its banned nuclear activity after the US quit the deal in 2016. Iran suspended IAEA inspections after Israel and the US bombed several of its nuclear sites and military bases in June. Under the nuclear Non-Proliferation Treaty, Iran is legally obliged to allow inspections of its nuclear sites, and on Friday the IAEA confirmed that they had resumed.
