The International Monetary Fund said in a report published Monday, Oct. 28, 2019, that political uncertainty and volatile oil prices are hindering economic growth in the Middle East this year. The region is reeling from U.S. sanctions on Iran and last month's attack on the world's largest oil processor in Saudi Arabia.
