The top diplomats of Britain, France, and Germany threaten 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.

France, Germany and the UK were signatories to the 2015 Joint Comprehensive Plan of Action (JCPOA) alongside the United States, China, Russia and the European Union. The accord required Iran to limit its uranium enrichment in exchange for sanctions relief.

The United Kingdom, Germany and France, known as the 'E3,' told the UN Security Council and the International Atomic Energy Agency that they are giving Iran until the end of August to address international concerns.
