U.S. intelligence officials have received threats that terrorists will strike a U.S. nuclear power plant on July 4. The officials are still checking the source's reliability.

The official said the threat is one of many filtering through U.S. intelligence and is not yet considered serious enough to formally warn the American public or change the nuclear industry's level of alert.

The threat, first reported by The Washington Post, was made against Pennsylvania's Three Mile Island and another plant in the Northwest.
