According to Col. Rabih Alenezi, he was given the order to drive out residents of a tribe in the Gulf state so that The Line, a component of the Neom eco-project, could be built.
After that, one of them was shot and murdered for demonstrating against the eviction.
Both the Neom management and the Saudi government declined to comment.
The $500 billion (£399 billion) Neom eco-region in Saudi Arabia is a component of the kingdom’s Saudi Vision 2030 plan, which intends to diversify the economy away from oil.
The Line, the company’s flagship project, is envisioned as a car-free city that is 170 km (106 miles) long and 200 m (656 ft) wide.
