Ancient wall found in Iran

Archaeologists in northern Iran have uncovered the remains of a 124-mile-long wall, the second longest such structure in Asia after the Great Wall of China.

Experts believe the wall in Golestan Province was constructed centuries ago, the Fars News Agency reported Monday. It was used to defend against by nomadic tribes from Central Asia, called the Ephthalites, who invaded the region in the 5th and 6th centuries.
