Rising Nile floodwaters are threatening to swamp an ancient archaeological site in Sudan, after some of the highest ever recorded river levels, archaeologists said Monday.

Teams have set up sandbag walls and are pumping out water to prevent damage at the ruins of Al-Bajrawiya, once a royal city of the two millennia old Meroitic empire, said Marc Maillot, head of the French Archaeological Unit in the Sudan Antiquities Service.

"The floods had never affected the site before," Maillot said.

The area includes the famous Meroe pyramids, a UNESCO World Heritage site.
