Hey, happy Thursday. I'm Carl Azuz. This is CNN Student News. It's your passport to 10 minutes of global headlines. Today we're spending time in North, Central and South America, but we start in the Middle East. The nation of Iran has a controversial nuclear program. Iran says the program is designed for peaceful uses, but other countries, including the U.S., believe Iran is trying to build a nuclear weapon. One thing we know for sure is that this program is moving forward. This is Iranian President Mahmoud Ahmadinejad in the middle of your screen. He was part of a presentation yesterday where fuel rods were loaded into the core of a nuclear reactor. These are the first nuclear fuel rods made inside Iran, so this is a big advancement for the country's nuclear program. The United Nations and European Union have put sanctions -- penalties -- on Iran in part because of its nuclear program. Those sanctions have been affecting Iran's economy and its citizens. President Ahmadinejad responded to the latest sanctions yesterday.
