Gaza, ALRAY - Israeli military vehicles penetrated into the southern Gaza Strip on Thursday morning, witnesses said, while the Palestinian resistance fired mortar shells in response without causing any casualties.

"Six military bulldozers accompanied by several tanks incurred about 200 meters from the border into farmland, as helicopters and spy planes circled above near the village of Khuzaa," east of the town of Khan Yunis, the witnesses said.

"Resistance fighters fired several mortar rounds at the Israeli forces and explosions were heard in the area," they added.

Similar incursions take place almost on a daily basis in the eastern and northern borders of the Gaza Strip in clear violation of the cease-fire- agreement that Israel signed with the Palestinian resistance brokered by Egypt in Cairo in the last November.
