Airport officials say current and ex-government officials have been banned from traveling without permission from either the state prosecutor or the armed forces.
The move comes a day after President Hosni Mubarak surrendered power to the military after an 18-day uprising by millions of protesters demanding his ouster and the introduction of sweeping democratic reforms. Mubarak's regime has faced long-standing allegations of corruption.
Officials say they have a list of officials from the former regime and have already prevented the information minister from leaving.
The officials spoke on condition of anonymity because they're not authorized to release the information.
