Current travel advice for Egypt
• There is extreme risk to security in the Sinai peninsula (with the exception of the Sharm el Sheikh resort areas) due to the threat from terrorism, kidnapping and criminal activity and we advise against all travel.
• There is extreme risk to security within 50 kilometres of the border with Libya (with the exception of the Siwa Oasis) due to the threat from terrorism, kidnapping and the presence of armed groups and we advise against all travel to this area.
