Four easyJet airliners in different locations across France had Arabic graffiti sprayed on their fuel panels, sparking a security alert. The sections of the aircraft are supposed to be secure and not accessible to the public. Arabic writing was also found on a bathroom door of one aircraft. EasyJet staff are on high alert and have been instructed to take extra security precautions.

EasyJet flies to 18 locations in France but for security reasons, officials are not releasing the locations the graffiti was discovered at. The contents of the graffiti are also not being released.

A spokesman for easyJet said the matter was not considered to be a threat and no passengers had to be removed from the aircraft. She said, “EasyJet assessed this issue, each time working in full consultation with the authorities, and is entirely satisfied it is nothing more than graffiti.”

“EasyJet takes very seriously any security related issue and would not operate a flight unless we are entirely satisfied it is completely safe to do so. “

Less than two weeks ago, ISIS terrorists killed 130 people in coordinated attacks in Paris.  It is also less than one month after a Russian airliner crashed in the Sinai Peninsula, killing all 224 on board. The Islamic state (ISIS) claimed responsibility and the plane is supposed to have crashed as the result of a bomb smuggled on board by ground crew.

EasyJet is a British low-cost airline carrier based in London’s Luton Airport. It is the largest airline of the United Kingdom by number of passengers carried. It operates domestic and international scheduled services on over 700 routes in 32 countries.
