The Syrian plane arrived at Athens around 12:00 p.m. local time to refuel, having obtained the necessary permits.
According to an airport official, an international embargo placed on Syrian President Bashar al-Assad's regime in May 2011 prohibited the airport from providing fuel to the Syrian plane. The Greek Foreign Ministry asserted "The problem is not due to the state civil aviation authority but due to two private companies that refused to provide the fuel."
The plane was ultimately refueled and departed Athens International Airport around 5:00 p.m. local time. Syrian state television reported that the delegation has arrived in Geneva.
The Geneva II peace talks on Syria are set to commence Wednesday.
