A senior Iranian official said on Saturday that proposals put forward by European powers at talks in Geneva about his country's nuclear programme were "unrealistic", suggesting that if they stuck to them it would be difficult to reach an accord.

Top diplomats from Britain, France and Germany met with Iran’s foreign minister in a last-ditch effort to avoid escalation in the Israel-Iran conflict.

European officials urged Iran to restrict its nuclear program hoping for off-ramp from conflict before President Trump decides whether to join Israel’s bombing campaign.
