This is the horrifying moment a man fell to his death on his birthday while posing on top of a cliff for a photo, writes dailymail.co.uk.

Footage shows Halil Dağ leaping down off a rock at the historic Urfa Castle in southern Turkey before losing his balance and tumbling off a cliff edge.

Despite scrambling to grab hold of something to stop his fall, the father-of-eight plunged 150ft, landing near a Kurdish restaurant at the bottom.

Video showed Halil leaping down over a barbed wire fence to pose for a picture at the historic site.

The clip captures him desperately trying to stay on his feet as he stumbled sideways.

To the horror of his friends, Halil, who was celebrating his birthday, then rolls off the cliff edge. 

Friends rushed over to help but it was too late. 

His devastated family later interred his body at the Abdurrahman Dede Cemetery, The Sun reported.
