TEHRAN - Iran's Foreign Minister Seyed Abbas Araghchi on Monday condemned a US decision to revoke Iraq's waiver to purchase electricity from Iran, calling the move "extremely deplorable" and accusing Washington of harming Iraqi civilians ahead of summer heatwaves.

In a social media post on X, Araghchi criticized the Trump administration for ending the exemption -- part of Washington's revived "maximum pressure" campaign against Tehran -- and said the decision would deprive Iraqis of "basic services" during critical months.

"The US administration is targeting innocent people by cutting their access to electricity, which is vital amid rising temperatures," Araghchi wrote, pledging Iran's continued support for Iraq.

He added that Tehran would collaborate with Baghdad to counter what he described as Washington's "unlawful actions."

Iraq, grappling with chronic power shortages after decades of conflict, relies on Iranian gas and electricity imports for over 40 percent of its grid supply despite its own oil wealth. The waiver had allowed Baghdad to continue energy purchases despite US sanctions on Iran.

The previous waiver expired on Saturday, and the US State Department opted not to renew it. Citing a February executive order by President Donald Trump, the department reaffirmed its commitment to increasing pressure on Iran, which Washington accuses of pursuing nuclear weapons -- a claim Tehran denies.
