The top diplomats of Britain, France, and Germany threatened to reimpose sanctions on Iran as an end-of-the-month deadline nears for the country to resume negotiations with the West over its nuclear program and cooperation with the United Nations nuclear watchdog.
The three countries, known as the E3, wrote in a letter to the United Nations dated Friday that they were willing to trigger a process known as the “snapback” mechanism, which allows one of the Western parties to reimpose U.N. sanctions if Tehran doesn’t comply with its requirements.
