Egyptian President Mohammed Mursi has said his country supports the Syrian revolution and that President Bashar al-Assad's administration had no place in Syria's future.
During a televised speech to Egypt's Shura Council, or upper house of parliament, Mr Mursi said: "There is no place for the current regime in the future of Syria."
President Assad has been losing ground to rebels waging a 21-month-old uprising.
Egyptians ousted their longtime authoritarian president, Hosni Mubarak, in a popular revolt in February 2011.
President Mursi won office in a free election earlier this year.
Syria's national airline cancelled a flight from Cairo to Aleppo today due to poor security conditions around the airport, Cairo airport officials said.
Meanwhile, Syria's national airline cancelled a flight from Cairo to Aleppo today due to poor security conditions around the airport, Cairo airport officials said.
Rebels fighting to overthrow President Assad said last week they would target Aleppo's international airport and opposition activists said there had been a big explosion near the complex overnight.
The SyriaAir flight had been due to fly to Aleppo before continuing to Damascus.
Instead, it flew straight to Damascus, the Syrian capital, after a five-hour delay, according to Cairo airport officials.
It was the first reported cancellation of a SyriaAir flight to the northern Syrian city.
Several foreign airlines have suspended flights to the capital, Damascus, since fighting erupted on the main airport road last month.
