An airport source said the incident occurred at the busy Terminal 2F at around 8:20 am (0620 GMT), when "a homeless man started bothering security agents and border police were called in to remove him".
Initially the man left while yelling curses but he soon returned and brought out a knife, when one of the officers fired his weapon.
"He was ordered to stop but kept advancing toward them, and an officer fired a single shot."
The man was quickly put on a stretcher and evacuated, the photographer said.
Security forces have been on high alert for terrorist attacks since a wave of jihadist killings that have killed more than 250 people since 2015, often by so-called "lone wolves" who often target police.
