The Foreign Office is urging British nationals in Cairo to stay away from the downtown area and Tahrir Square following a violent demonstration which left 24 people dead and more than 200 injured.
In the worst clashes since the 18-day uprising in Egypt in February, that led to the resignation of Egypt president Hosni Mubarak, hundreds of people protesting against an attack on a church in the south of the country fought with more than 1,000 security force personnel.
The Foreign Office said visitors to Cairo should stay away from the downtown area and the streets around Tahir Square, the focal point of demonstrations earlier this year, and to avoid any further demonstrations.
It also warned that there has been disruption to flights at Cairo airport due to an air traffic control dispute, but this has now ended.
