The foreign ministers of Germany, France and Britain plan to hold nuclear talks with their Iranian counterparts on Friday in Geneva, a German diplomatic source told Reuters.
The ministers will first meet with the European Union's top diplomat, Kaja Kallas, before holding a joint meeting with the Iranian foreign minister, the source said.
The European initiative comes amid fears of a growing conflict in the Middle East, after Israel launched widespread military strikes against its arch-enemy, Iran, last week and Iran carried out retaliatory attacks on Israeli targets.
US President Donald Trump has refused to say whether the United States will join its ally Israel's military campaign, fueling concerns that the crisis could intensify.
The aim of the talks between Iran and the Europeans, which the German source said are being held in coordination with the United States, is to convince the Iranian side to firmly guarantee that it will use its nuclear program only for civilian purposes.
According to the source, the talks will be followed by a structured dialogue at the expert level.
Israel has said its goal is to eliminate Tehran's ability to develop a nuclear weapon. Iran denies that its nuclear program is for military purposes.
German Chancellor Friedrich Merz has spoken out in support of Israel's attack and angered Tehran this week by saying the Iranians must de-escalate or face the threat of even greater destruction.
Meanwhile, German Foreign Minister Johann Wadephul on Wednesday called on Iran's leaders to work towards a solution that would include guarantees over its nuclear program, telling them that "it is never too late to sit down at the negotiating table."
