Germany urges Iran to resume nuclear talks

"We vehemently ask Iran to return to the negotiating table constructively and as soon as possible," a ministry spokesperson told a briefing.

"We are ready to do so, but the time window won't be open indefinitely."

Last month, France, Germany, and Britain voiced grave concern about IAEA reports confirming that Iran has produced uranium metal enriched up to 20% fissile purity for the first time and lifted production capacity of uranium enriched to 60%.
