About five IDF tanks and bulldozers moved into the mostly empty Abasan area near the southern Gaza town of Khan Younis on Saturday, Palestinian security officials said. There were no reports of fighting or casualties. IDF troops had already taken up positions in vacant areas near the town of Rafah, but the move into Abasan was the first time troops entered the Gaza Strip north of that area. The troops crossed the border with Israel and moved several hundred meters into Abasan on Saturday afternoon, the security officials said. The army said the raid in Abasan was a limited operation and the soldiers were expected to leave soon.
