Sudan: Heritage sites destroyed by gold-diggers
The ruins, that were two thousand years old, have been destroyed by treasure hunters who searched the site for gold.
To save time, they used heavy machinery, digging a vast trench into the historic location. Hardly anything remains.
"We worked on this site for a month," said the archeologist Habab Idriss Ahmed.
"At the time, it was a quiet and beautiful site, never touched by anyone. But today, when I came here, I was shocked by the way it has been destroyed."
Sudan counts around a thousand well-known sites, a hundred of which have been damaged or destroyed by gold diggers.
"There are a lot of attempts to attack archaeological sites," explained Hatem al-Nour, Sudan's director of antiquities and museums.
"This attack is a strong coup because this site is a rare site that contained a lot of useful information for research on the history of Sudan."
The destruction of heritage sites is a serious problem in Sudan, where treasure-hunters can be freed by the police without charge.
Businessmen finance digging expeditions and local authorities have even encouraged people to hunt for treasures.
