An AP photographer on the site saw several busloads of police officers under the famous tower. An officer on the site says the tower and the nearby Champs de Mars park have been evacuated but has declined to give any other details. About 2,500 people were affected.
Tourists are still on the nearby sidewalks, however, and road traffic continues to circulate.
French media reported that Tuesday's evacuation followed a bomb alert. Further information was not immediately available. Paris police headquarters did not return numerous calls.
