Operation "Autumn Clouds" (Hebrew: מבצע ענני סתיו‎ Mivtza Ananei Stav) is an Israeli military operation that began on 1 November 2006, following numerous rocket and mortar attacks on southern Israel, when the Israeli Defense Forces entered the Gaza Strip triggering sporadic fighting near Beit Hanoun. The operation is the largest military endeavor undertaken by the Israeli military since Operation "Summer Rains" in the summer of 2006.
