Verizon says it has filed a court challenge to new federal regulations that prohibit broadband providers from interfering with Internet traffic flowing over their networks.

A divided Federal Communications Commission adopted the "network neutrality" rules last month. Verizon Communications filed the challenge Thursday in federal appeals court in the District of Columbia, it says.

The new rules prohibit phone and cable companies from favoring or discriminating against Internet content and services that travel over their networks -- including online calling services such as Skype, Internet video services such as Netflix and other applications that compete with their core businesses.

In its court filing, Verizon argues that the FCC overstepped its authority in adopting the regulations.

The new rules are also expected to be challenged by Republicans in Congress.
