 The tour guides are no longer allowed to lecture inside the tombs, and visitors are expected to proceed quietly and in single file through the tombs.This is to minimize time in the tombs and prevent the crowds from damaging the surfaces of the decoration.In 1997, 58 tourists and four Egyptians were massacred at nearby Deir el-Bahri by Islamist militants from Al-Gama'a al-Islamiyya.
