Police sappers were required to detonate an old artillery shell uncovered during tunneling work for a new train line to Jerusalem on Monday.
The shell was discovered at the entrance to Jerusalem, close to the Sakharov Gardens interchange on Route 1, which connects the capital with Tel Aviv. The road was closed for several hours until sappers could neutralize the shell.
Laborers doing work for the Arazim Tunnels complex made the discovery, and police bomb removal experts exploded the shell in a controlled detonation.
The Arazim valley complex, to the west of Jerusalem, will feature tunnels for a new high-speed rail between the capital and Tel Aviv. A road also runs through tunnels in the valley, connecting the Ramot neighborhood to Route 1.
There were no details on when or how the shell came to be where it was.
