Israeli army started on Monday afternoon digging a five-meter-trench by the separation wall in the Salfit area, in the northwest of the West Bank.
The trench is being dug on the Palestinian side of the wall.
Bulldozers damaged agricultural areas and cut dawn trees. Eywitnesses said Israeli bulldozers have also taken the cut trees and the rocks to use them for constructing a road on the other side of the wall in that area.
