The FOC give advice on how to keep safe if you decide to go to Egypt.
– The Foreign and Commonwealth Office
You should follow the regulations set by the local authorities and obey curfews. Make sure you keep valid photographic identification with you at all times.
If you are already in a part of Egypt where the FCO advise against all but essential travel, you should consider whether you have a pressing need to remain. If you decide to remain in Egypt, you should stay at or close to home or a place of safety (e.g. your hotel), keep a low profile and pay close attention to your personal safety, particularly in the larger cities. You should avoid crowds.
