Ancient city discovered in India
The remains have been discovered at Sisupalgarh near Bhubaneswar, capital of the eastern state of Orissa.
Researchers say the items found during the excavation point to a highly developed urban settlement.
The population of the city could have been in the region of 20,000 to 25,000, the archaeologists claim.
The excavations include 18 stone pillars, pottery, terracotta ornaments and bangles, finger rings, ear spools and pendants made of clay.
But some historians and archaeologists in Orissa have expressed reservations about the claim of the researchers - they say it is too early to say anything about the population or periodicity of the area.
