Many countries are warning their nationals against all but essential travel to Egypt.
Many of those already there are attempting to leave the country, only to find that scores of flights have been disrupted.
Travel warnings are in force for mostly Cairo, Alexandria and Suez.
However, some foreigners say they do feel it is safe enough to stay, saying the anger so far appears to be limited towards symbols of the regime.
One American tourist said on euronews: “The worst thing was no internet and no phone service, that was the worst thing. At least with the internet you could contact your family but we had no internet service so that wasn’t good. (…) Egypt in general is a safe place. And it’s not terrorism. It’s, you know, protest, so there’s a big difference.”
As a precaution, the Egyptian army has posted troops outside musuems, amid increasing reports of looting and ransacking of public buildings.
Residents have also been seen forming groups to watch over smaller museums and historic monuments.
