Saudi Crown Prince Unveils Latest Vision for Controversial Neom Megacity.

Saudi Arabia has released new images of its $1tn Neom megacity, which is being built in the northwest of the country. The city is being billed as a tourism attraction and global hub for technology and innovation, and will run entirely on renewable energy. However, human-rights groups have raised concerns about the city's plans for mass surveillance, and the UN has accused Saudi Arabian officials of evicting a tribe from the area without adequate compensation. Critics also believe that the scale and ambition of the project mean it may never be fully realised.
