Safety in Egypt

Terrorism has affected the industry in recent times. A total of 58 foreign tourists were killed in the 1997 Luxor massacre. The tourist industry sunk even lower with the September 11 attacks in the eastern United States in 2001, the 2004 Sinai bombings, April 2005 terrorist attacks in Cairo, the July 23, 2005 Sharm el-Sheikh attacks, and the 2006 Dahab bombings.

Historically, foreign tourists have been a common target of attacks dating back to the early 1990s. Militants have typically been motivated by a combination of Qutbism and opposition to the Mubarak government, and attacking foreigners including non-Muslims while hurting Egypt's tourist trade was seen as serving both goals.
In late 2010 Egypt's tourism ministry decided to close the Sharm el-Sheikh beach following shark attacks that left one German tourist dead and four people (three Russians and one Ukrainian) seriously injured.
The attacks appear to be from more than one shark, and include at least one shortfin mako shark. Marine biologist George Burgess said that more than one species of shark has been involved in the attacks, possibly including an Oceanic whitetip shark.
