Israeli army Saturday opened fire on Palestinian farmers near the security fence in southeast Gaza Strip and sent ground troops into the northern area of the coastal enclave, Xinhua reported.
The Palestinian farmers were working in their fields in al- Faraheen area, east of Khan Younis city, when they came under machine gun fire from the Israeli army posts on the border, witnesses said.
According to security sources, machine gun fire was also recorded on the border line in northeast Gaza Strip and the east of Jabaliya town.
There were no casualties in the two shooting incidents.
Meanwhile, three Israeli bulldozers, backed by two tanks, rolled for a few hundred of meters into Beit Lahiya town, an agricultural community in northern Gaza Strip. Residents said the bulldozers leveled some groves and withdrew later on Saturday morning.
Palestinian militants fired three mortar shells at the invading troops in Beit Lahiya. The military wing of the Popular Resistance Committees (PRC) claimed responsibility for the mortar attack.
Earlier, Israeli sources said two rockets, fired from Gaza, landed in an open area in Western Negev, causing no casualties.
In late December 2008, Israel launched the toughest offensive in the Hamas-controlled Gaza Strip, killing more than 1,300 Palestinians and destroying thousands of houses and Hamas-run governmental buildings.
Since the end of the 22-day offensive, the security situation on the Gaza borders remains tense despite quietness as Egypt is still trying to renew a ceasefire between Israel and Palestinian militant groups.
