In September 1997, nine German tourists were shot in Cairo in a terrorist attack, followed two months later by the death of 67 people (57 of them tourists) in Luxor. Since that time, however, law enforcement units have cracked down on the activities of fundamentalist Islamic militant groups and other extremists and not a single tourist has been killed by terrorists in Egypt since 1997. Most visitors have hassle-free stays, but travellers are warned to avoid public political gatherings and demonstrations.
