The core numerical claim is directly supported by the fetched Bloomberg article, "OPEC Output Fell Most in Decades Last Month on War, Survey Shows," which states that OPEC output fell by 7.56 million barrels per day, about 25%, to 22 million barrels per day in March. The same source also specifically names Saudi Arabia, the United Arab Emirates, and Iraq as countries forced to slash production. While the exact phrasing that Iraq recorded the largest decline is not explicitly visible in the fetched excerpt, Bloomberg identifies Iraq as one of the main countries behind the drop and the broader claim substantially matches the article. The Odaily page could not be validated, and the X link could not be fetched, so confidence is not high despite strong support from Bloomberg.
