France, the UK, and Germany have warned that they will trigger the UN’s ‘snapback’ mechanism to reinstate prior sanctions on Iran unless significant progress is made on nuclear talks by the end of summer. The 2015 Joint Comprehensive Plan of Action (JCPOA) had relaxed sanctions in exchange for nuclear oversight. The UN-authorized agreement is set to expire on October 18. Following a joint Israeli-US strike on an Iranian nuclear facility last month, the E3 bloc and EU diplomats held their first virtual meeting with Iran's foreign minister. The timeline for a sixth round of Iran-US negotiations remains unclear.
