Passengers arrive in the UK from 'frightening' Cairo

British nationals in Cairo, Alexandria and Suez are being told to leave if it is safe for them to do so, following days of violent protests across Egypt.

But despite upgrading its advice, the Foreign Office (FCO) is not currently organising a formal evacuation.

Passengers arriving at London's Heathrow Airport from Cairo told the BBC's Nicola Pearson about their "frightening" experiences in Egypt.
