Israel Air Force aircraft struck a terror cell preparing to launch rockets into Israel from the Gaza Strip on Friday, according to the IDF Spokesman's Office.The strike came after two rockets were fired into southern Israel from Gaza earlier in the day, landing in the Eshkol Regional Council area. More than 130 rockets have been fired into the South from Gaza since Monday, but Thursday and Friday were relatively quiet after an Egyptian-brokered informal ceasefire seemed to be largely holding. Four additional rockets landed in the Sdot Negev and Eshkol Regional Council areas following the IAF strike, causing no injuries or damage. Hamas officials said that one Palestinian was killed and two others were wounded in Friday's IAF strike at al-Bureij refugee camp in central Gaza. The Popular Resistance Committees, terrorists often involved in shooting rockets, said the man killed in the attack belonged to their group.Palestinian sources claim that this marked the ninth Palestinian death from IAF strikes since hostilities began Monday.Israel on Thursday lodged an official complaint with the United Nations about the rocket fire into southern Israel from the Gaza Strip.Ambassador to the UN Ron Prosor complained to UN Secretary-General Ban Ki-moon that “the lives of about a million Israelis are paralyzed” by the projectiles.Three rockets were fired into Israel on Thursday night, one of which was intercepted by the Iron Dome rocket-defense system. They marked the first such attacks since early Thursday morning when seven missiles hit Israel, in addition to one that was intercepted by the Iron Dome near Ashkelon. Prosor stated that “as long as Israel’s southern communities will not know quiet, it will not be quiet in Gaza.”He added that Israel fully cooperates with the UN, allowing civilian material and humanitarian aid into Gaza, “and in exchange weapons continue to flow into the Strip and rockets are fired into Israel.”Yaakov Katz and Reuters contributed to this report.
