The Foreign Office have advised against all but essential travel to Cairo (all four governorates, including Giza), Alexandria, Luxor and Suez. The nationwide curfew has been extended from 1500-0800 local time. They recommend that British nationals without a pressing need to be in Cairo, Alexandria or Suez leave by commercial means where it is safe to do so. British nationals in other areas of Egypt where there are demonstrations should follow the advice below and stay indoors wherever possible.
The situation in Sharm el Sheikh is currently being reported as calm, although there are some disruptions to flight schedules. Anyone travelling to, through or from Egypt are advised to confirm your travel plans. You should not travel to the airport without having a confirmed flight.
