Israeli forces on Saturday rolled into the southern Gaza Strip and Palestinian fighters engaged them, witnesses said, according to DPA. A number of tanks and bulldozers entered the Khoza'a area in eastern Khan Younis city in the southern Gaza Strip. The bulldozers started to level the land, destroying fields and farms in the area, residents said. The troops withdrew around the noon after Gaza militants said they exchanged fire with the forces. There were no reports on casualties. During the operations, the Israeli forces detonated two explosive devices that were planted by Palestinian fighters near the security fence which separates Israel and Gaza.
