Until the mid-twentieth century, non-Muslims were not permitted in the area. Since 1967, non-Muslims have been permitted limited access; however non-Muslims are not permitted to pray on the Temple Mount, bring prayer books, or wear religious apparel. The Israeli police help enforce this. Israel restricted access for a short time during 2012 of Palestinian residents of the West Bank to the Temple Mount. West Bank Palestinian men had to be over 35 to be eligible for a permit. Palestinian residents of Jerusalem, who hold Israeli residency cards, and Palestinians with Israeli citizenship are permitted unrestricted access.
