Move to stop permitting Iraqi purchases of Iranian energy will tighten sanctions but stress a U.S. partner in the region.

Iran said it would not negotiate under "intimidation", after US President Donald Trump sought to ratchet up pressure on Tehran by ending a sanctions waiver that had allowed Iraq to buy electricity from its Shi'ite neighbour.

Iran’s foreign ministry on Monday condemned the United States for rescinding a waiver allowing neighboring Iraq to import gas from Iran.
