Images from the Rogun dam in Tajikistan, which is expected to be the world’s tallest when completed.

Tajikistan has begun building what is expected to become the world’s tallest dam. At a planned 335m tall (1,100 feet), Rogun would be higher than Jinping-1 Hydropower Station in China (305m), reports the BBC’s Sohrab Zia.

Tajikistan, Central Asia’s poorest country, has suffered from electricity shortages for years.

Rogun is meant to put an end to that, producing enough power to satisfy the country’s energy needs with electricity to spare for export to Afghanistan and Pakistan.

The Rogun hydropower project will dam the Vakhsh river which flows through many steep gorges in the Pamirs, and managing its strength is one of the engineering challenges.

Guests at a ceremony inaugurating the project released doves in a gesture of peace. Tajikistan’s downstream neighbours have been fiercely critical.
