This is the moment passengers are thrown through the air as their minibus overturns and rolls into a ditch following a horrific crash.

Terrifying onboard footage captured the split-second chaos as a tourist minibus collided with a passenger coach on the Isparta–Afyonkarahisar highway in Turkey around 5:50am on Sunday, 25th May.

The impact sent the minibus spinning off the road and flipping into a ditch, with screaming passengers hurled from their seats.

The footage shows passengers jolted violently out of their seats, some slamming into the roof and windows as the vehicle rolled down the embankment.

The minibus, driven by Mehmet Akgun, was carrying domestic tourists when it was struck by the larger coach, driven by Ramazan Acan.

The force of the collision flipped the smaller vehicle completely, leaving it on its side in a crumpled heap.

Emergency crews arrived to find debris scattered across the roadside and stunned passengers crawling from the wreckage.

Twenty-eight people were injured, one of them critically.

Authorities have launched an investigation into the cause of the crash, which happened at a known accident blackspot.
