Still current at: 7 November 2014Updated: 7 November 2014Latest update: Safety and security section (North Sinai) - a state of emergencyand curfew declared
Download map (PDF)
There is a high threat from terrorism. Three South Korean tourists andtheir driver were killed at Taba (Sinai) on 16 February, and the groupresponsible has threatened further attacks. See below for more detail.
The Foreign and Commonwealth Office (FCO) advise against all travelto:
the Governorate of North Sinai due to the significant increase incriminal activity and recent terrorist attacks on police and securityforces that have resulted in deaths
The FCO advise against all but essential travel to:
the Governorates of Beni Suef, Minya, Asyut and Sohag
the Governorate of South Sinai, with the exception of the areawithin the Sharm el Sheikh perimeter barrier, which includes theairport and the areas of Sharm el Maya, Hadaba, Naama Bay, SharksBay and Nabq
within 50km of the border with Libya
the area west of the Nile Valley and Delta Regions, excluding Siwa,Fayoum and the coastal areas (as shown on the map)
The area to which the FCO advise against all but essential travel doesnot include the tourist areas along the Nile river (eg Luxor, Qina,Aswan, Abu Simbel and the Valley of the Kings).
Terrorism
We believe that terrorists continue to plan attacks. Attacks could beindiscriminate and could occur without prior warning. Terrorists couldtarget protestors and the Egyptian authorities. Attacks have mainlybeen aimed at the security forces, their facilities and other governmentbuildings. You should take great care near these buildings. Attackstargeting foreigners in tourist resorts and elsewhere can’t be ruled out.
A recent anonymous posting on a jihadist website encouraged attacksagainst British and other western teachers and schools in the MiddleEast, and specifically referred to the Maadi suburb of Cairo. The FCO isunaware of any specific threat against any school or individual in Egypt.Nonetheless, the FCO is encouraging British schools and schools withlarge numbers of British teachers to review and enhance their securityposture. You should remain vigilant and alert to local securitydevelopments.
On 21 September, an IED attack killed two police officers and injuredseveral others in a street close to Ministry of Foreign Affairs in centralCairo.
On 19 July, an armed group attacked a security checkpoint along theFarafra-Bawati road in the New Valley governorate, killing 22 borderguards. And on 5 August, 5 people were killed in an attack on asecurity checkpoint vehicle along the coastal road east of Dabaa, inthe Matruh Governate.
There were a number of explosions in Cairo on 25 June, including atsome Metro stations. There are reports of injuries. Metro services weresuspended temporarily but have now resumed.
On 2 May 2014, there were bomb blasts in El Tor (Al Tur) in South Sinaitargeting a police check point and a bus. On the same day there was anexplosion outside a court building in Heliopolis in Cairo. There were anumber of deaths and injuries.
On 16 February, 3 South Korean tourists and their driver were killed inan attack on a bus in Taba (Sinai). See Terrorism
Sharm el Sheikh
Enhanced security measures are in place to protect the Sharm elSheikh resort areas. Egyptian military are situated in Sharm el Sheikhinternational airport, at check points around the perimeter of Sharm elSheikh and throughout the South Sinai Governorate. Routine securitychecks are being performed on entry into the airport and the police arecarrying out vehicle checks in Sharm el Sheikh. There were no violentprotests in the South Sinai resorts during recent disturbances inEgypt.
Hurghada
Enhanced security measures are in place to protect the resort areas inHurghada. Egyptian military are situated in and around Hurghadainternational airport. There are checkpoints around Hurghada andthroughout the Red Sea Governorate. There are roadblocks in place inthe town and monitoring of areas often frequented by tourists. InHurghada on 14 August 2013 there were some violent clashes, in anarea away from tourist resorts. One man was killed.
Protests and demonstrations
Protests, marches and demonstrations are common across Egypt.Demonstrations often happen on Fridays, but can occur at any timeand with little prior notice.
The atmosphere at demonstrations can change quickly and withoutwarning. Police may use water cannon, tear gas, birdshot or liveammunition for crowd control.
There have been several violent clashes since July 2013 resulting in alarge number of deaths. Most of the clashes have taken place in Cairoand Alexandria. At protests in Cairo, Alexandria and Fayoum on 24 and25 January 2014 there were reports of around 80 deaths. There areongoing protests and clashes within university campuses across thecountry.
If you become aware of any nearby protests, leave the areaimmediately. Don’t attempt to cross road blocks erected by thesecurity forces or protesters. Make sure you keep valid photographicidentification with you at all times. Take particular care in areas with ahistory of regular protests. At protests on 24 and 25 Januarywesterners, including British Nationals, were singled out and attackedby some protestors.
There is a serious risk of violence and sexual assault atdemonstrations. NGOs report more than 100 rapes and sexualassaults against women in demonstrations since 30 June 2013.Foreign and Egyptian women have been attacked. See Safety andsecurity
