GAZA CITY, Palestinian Territories: Israeli aircraft struck a Hamas facility in the southern Gaza Strip on Friday after cross-border mortar fire, the Israeli army said, as violence continued for a third day. “In response to the ongoing attacks against Israeli forces, Israel Air Force aircraft targeted a Hamas terror infrastructure,” an army statement said. Palestinian witnesses said there were two sets of air raids, one targeting Beit Lahia in northern Gaza and the second in Khuzaa, southeast of Khan Yunis, in the south of the territory. There were no reports of any casualties. It was the fourth air raid on Gaza since Wednesday, when direct clashes between Hamas and Israeli forces broke out for the first time since a devastating 2014 war.
