The European Commission says it has opened an anti-trust investigation into the way the U.S. computer company Apple sells music on its Internet-based music store in Europe.
The E.C. said Tuesday that Apple's iTunes and its partner music companies prohibit users in one country from downloading music from a Web site set up for users in another country.
It also says the companies charge different prices for the same songs sold in different countries.
The commission says these territorial sales restrictions violate European Union competition rules.
Apple has two months to respond to the E.C. charges.
