Israeli forces on Saturday opened fire at Palestinian farmers near the security fence in south-east Gaza Strip and sent ground troops into the other end of the coastal territory, according to eyewitness accounts quoted by DPA. The farmers were working their land in the Faraheen area in the east of Khan Younis city in the southern Gaza Strip when they came under machine gun fire from the Israeli army posts on the border, the witnesses said. Meanwhile, three Israeli bulldozers, backed by two tanks, rolled for a few hundreds of meters into Beit Lahiya town, an agricultural community in the northern Gaza Strip. Residents said the bulldozers leveled some groves and withdrew later in the morning.
