US orders evacuation of its’ diplomatic staff from Egypt
US government orders evacuation as another US citizen is killed during clashes in Egypt
The US has warned Americans not to travel to Egypt and has told non-emergency diplomatic staff to leave, as clashes continue in the country.
The state department also urged US nationals in Egypt to remain alert.
The warning came as at least three people - including a US citizen - died in clashes between supporters and opponents of President Mohammed Morsi.
Tensions have been rising ahead of a mass rally planned by the opposition on Sunday to demand Mr Morsi steps down.
In a warning on Friday, the US state department said it had "authorised the departure of a limited number of non-emergency employees and family members" from Egypt.
It asked Americans "to defer non-essential travel to Egypt at this time due to the continuing possibility of political and social unrest".
Cairo's main airport was packed with departing passengers, and all flights leaving for Europe, the US and the Gulf were fully booked, officials were quoted as saying.
