Here is a picture of one screen with a hacked message in Arabic. This appears on all the screens in the airport now:

"In the name of God and the people, Rafik Hariri Airport is not the airport of Hezbollah and Iran, with Hassan Nasrallah. 

You will not find a supporter. 

If Lebanon is entangled in a war, you will bear responsibility and its consequences. 

Hezbollah, we will not fight on behalf of anyone. 

You bombed our port and now you want to bomb our airport because of the introduction of weapons. 

Let the airport be freed from the grip of your evil!"
