Paris, Sha'ban 4, 1436, May 22, 2015, SPA -- Staff at the Eiffel Tower refused to open the most visited paid monument in the world Friday because they said they are threatened by bands of pickpockets, according to dpa. The pickpockets operate in groups and are sometimes aggressive. In response to the protest, the company that operates the Eiffel Tower said it would work closely with police to guarantee the safety of its personnel and visitors. -- SPA 20:19 LOCAL TIME 17:19 GMT www.spa.gov.sa/w
