This is the second video with Ohel released during September.
In the now released clip, Alon Ohel asks Israel's Prime Minister to ensure that all hostages are released. But in the pictures, a Hamas member can also be seen standing next to him, with a pistol on his shoulder.
It is not established when the film was recorded.
"Our family is shaken and suffering", say his parents Idit and Kobi Ohel in a statement that continues: "It is obvious that Alon has lost vision in his right eye and he looks thin".
They say that Hamas is responsible for keeping their son alive but also that his and the entire hostage's fate lies in Prime Minister Benjamin Netanyahu's hands.
