Germany warned Wednesday that Iran's decision to suspend cooperation with the International Atomic Energy Agency (IAEA) sends a “disastrous signal” for diplomacy, just hours after Iranian President Masoud Pezeshkian ratified a law passed by parliament to halt coordination with the UN agency.

A spokesperson for Germany’s Foreign Ministry said: “For a diplomatic solution to the nuclear issue, it is essential that Iran work with the IAEA.”

The move follows escalating tensions after the 12-day war that began on June 13, during which Israel launched strikes on Iranian nuclear and military facilities and the United States bombed three key nuclear sites. On June 25, Iran’s parliament passed the bill suspending cooperation, which was later approved by the Guardian Council and formally enacted by Pezeshkian this week.

According to Iranian media, the law aims to protect Iran’s rights under the Nuclear Non-Proliferation Treaty (NPT), particularly regarding uranium enrichment. Iran claims its nuclear program is peaceful, while Western powers and Israel suspect it of seeking a nuclear weapon.

Israeli Foreign Minister Gideon Sa’ar responded by calling on the international community—particularly Germany, France, and the UK—to act decisively and reimpose all sanctions on Tehran. “The world must act now and use every tool to stop Iran’s nuclear ambitions,” he said.
