The Eiffel Tower was closed once again Tuesday after workers raised security concerns in the wake of the Paris massacre, NBC News reported.
The closure came a day after the attraction reopened following Friday's terror attacks and was lit in colors of the French flag.
Despite heightened security, discussions about further safety measures were still taking place with employees, the landmark's operator Societe d'Exploitation de la Tour Eiffel (SETE) said.
"The main subject of the talks are security measures that must be put in place to ensure that both visitors and staff are safe," a spokeswoman told NBC News.
