Among the top 10 hottest countries in the world on Saturday, El Dorado Weather cited Iraq, Kuwait, and Oman as the top three Arab nations.

Saudi Arabia will experience a heatwave with temperatures expected to reach 50 degrees Celsius in some regions, while Amara, a city in south-eastern Iraq, recorded a blistering 50 degrees Celsius.
