Iraq's Prime Minister Mohammed Shia al-Sudani told Iranian President Masoud Pezeshkian on Wednesday that attacks targeting Iraq were unacceptable.

He told Pezeshkian that the attacks undermined efforts to end the war and return to dialog, according to a statement by the prime minister's office.

Iraq has been among a number of countries in the region targeted by Iran in response to U.S. and Israeli strikes. 

Iran attacked commercial ships on Wednesday and targeted Dubai International Airport, escalating a campaign of bottling up the oil-rich Persian Gulf as global energy concerns mounted and American and Israeli airstrikes pounded the Islamic Republic.

Iran’s response to the surprise Israeli and U.S. bombardment 12 days ago has upended trade routes, choked supplies of fuel and fertilizer coming out of the Gulf and threatened air traffic through one of the world’s most-traveled regions. Both sides have dug in, hoping to outlast the other.

The fallout across the Middle East has widened as Israel strikes what it says are targets connected to Iran-backed Hezbollah militants in Lebanon. The U.N. refugee agency said at least 759,000 people have been internally displaced in Lebanon, while more than 92,000 others have crossed into neighboring Syria.
