The United Nations has reimposed a wide range of sanctions on Iran, effective September 27 at 8pm EDT, due to Tehran's failure to meet its nuclear commitments, according to the US Department of State.

• The sanctions were enforced under six previously adopted UN Security Council resolutions.
• The measures are backed by the US, France, Germany, and the United Kingdom.
• The restored resolutions require Iran to halt uranium enrichment and reprocessing, prohibit ballistic missile technology, and reimpose an arms embargo.
