One of the top floors of the Eiffel Tower was on fire Tuesday, officials said. Smoke could be seen rising from the famous Paris monument.
Officials said they were not sure whether anyone was on the top level, where the fire appeared to have erupted.
The company that operates the Eiffel Tower confirmed the fire but gave no details as to its origin and had no information about whether anyone may have been injured in the blaze, which appeared to be limited to a top floor of the monument.
The 324-meter (1,069-feet) iron-laced tower draws 6 million visitors a year, making it the world's most popular paying tourist attraction.
The tower was built by Gustav Eiffel for the 1889 World's Fair.
