Initiating the snapback mechanism against Iran over nuclear concerns could risk escalating tensions at a time when diplomacy has stalled

Britain, France and Germany launched a 30-day process to reimpose UN sanctions on Iran over its nuclear programme on Thursday, a step likely to stoke tensions two months after Israel and the United States bombed Iran, according to a letter sent by E3 to the UN Security Council seen by Reuters.

The trio, known as the E3, said in a statement they had decided to trigger the so-called snapback mechanism before they lose the ability in mid-October to restore sanctions on Tehran that were lifted under a 2015 nuclear accord with world powers.

They have held several rounds of talks with Iran since Israel and the United States struck its nuclear installations in mid-June, aiming to agree to defer the mechanism, but they deemed that talks in Geneva on Tuesday did not yield sufficiently tangible commitments from Iran.
