Iran’s foreign minister, Abbas Araghchi, warned Friday that Israel will face serious consequences following strikes on major Iranian nuclear-related facilities.

In a social media post, Araghchi said the attacks targeted critical infrastructure and accused Israel of acting alongside the United States. “Israel has hit 2 of Iran’s largest steel factories, a power plant and civilian nuclear sites among other infrastructure. Israel claims it acted in coordination with the U.S.,” he wrote, adding that the “attack contradicts [President Trump’s] extended deadline for diplomacy.”

He further declared, “Iran will exact HEAVY price for Israeli crimes.”

The warning came after the IDF confirmed that Israeli forces carried out strikes on a heavy water facility in Arak and a uranium extraction plant in Yazd.

According to the IDF, the Arak site had previously been targeted during Operation Rising Lion last June, and intelligence had since detected attempts by Iran to rebuild the facility. “repeated reconstruction attempts by the Iranian terror regime have been identified. Therefore, the IDF has now struck the facility once again.”

Regarding the facility in Yazd, the IDF said it plays a key role in processing raw materials that are later used in uranium enrichment, an essential step in nuclear development.

The escalation comes as President Donald Trump announced Thursday that the United States would delay planned strikes on Iranian energy infrastructure for an additional 10 days to allow more time for negotiations, setting a new deadline of April 6.

“As per Iranian Government request, please let this statement serve to represent that I am pausing the period of Energy Plant destruction by 10 Days to Monday, April 6, 2026, at 8 P.M., Eastern Time,” Trump wrote in a post on Truth Social.

In a subsequent interview with Fox News, Trump said the extension was granted after Iranian officials sought more time through intermediaries ahead of a potential escalation.

“They asked for seven, and I gave them 10,” he said, adding that talks were ongoing and “going fairly well.”

Trump cautioned that if Iran does not meet U.S. expectations, additional strikes could be carried out, including against key infrastructure such as power plants.
