Archaeologists say artifacts discovered in an ancient drainage tunnel under Jerusalem are left over from war 2,000 years ago.

On Monday, archaeologists presented a Roman legionnaire's sword and sheath found in the tunnel last month. They believe it dates to around 70 A.D., when Rome put down a Jewish revolt, razing the second biblical Jewish Temple and much of the city, the Associated Press reported.

In a futile attempt to escape the Romans, accounts of battle say Jewish rebels fled to the tunnels.

Israel Antiquities Authority rchaeologist Eli Shukron said diggers also found clay lamps, pots, and a bronze key. He thinks rebels left many of those items.

The newly excavated tunnel is part of a growing network of subterranean passages under the city.
