The Eiffel Tower and the surrounding park were evacuated on Tuesday for the second time in two weeks after a bomb alert. The city's police headquarters said an anonymous caller phoned in a bomb threat Tuesday from a telephone booth near the tower.
Last week, France's national police chief said the country was facing a "peak" terror threat, and that authorities suspect al-Qaida's North African affiliate of plotting a conventional bomb attack on a crowded target.
That was preceded a week earlier by a false bomb alert at the Eiffel Tower, and investigators are looking into an anonymous phone call that prompted police to evacuate the most-visited monument in the tourism-oriented country.
