Some 2,000 army reservists have been called back up to IDF service following the resumption of hostilities by Gazan terrorists on Tuesday.
Most of the reservists are being called up to supplement regular forces already mobilized in the Gaza region.
At least 60 rockets have been fired into Israel since Hamas broke yesterday's ceasefire by first firing at communities in southern Israel and then, following an IDF retaliation, launching a massive missile barrage at major Israeli cities throughout the country.
15 of the rockets fired since Tuesday have been intercepted by the Iron Dome missile defense system over civilian population centers, while the rest fell in open areas.
No injuries were reported, although millions of Israelis once again found themselves confined to bomb shelters and a car in central Israel was damaged by falling shrapnel from an intercepted rocket.
Hamas's "military wing", the Ezzedine al-Qassam Brigades, said that in addition to attacking southern communities with short- and medium-range Qassam and Grad rockets, it fired several domestically-produced M-75 rockets and Iranian-made Fajr 5 rockets at cities in central Israel. The terrorist faction also claimed to have fired a long-range J-80 rocket towards Ben Gurion airport, although that claim could not be confirmed.
Rockets also targeted Beit Shemesh and the Jerusalem region.
Responding to the attacks, the Israeli Air Force hit several terrorist positions in Gaza - including an attempt to kill Ezzedine al-Qassam's elusive leader, Mohammed Deif.
Hamas official Mousa Abu Marzouk claimed Deif's wife and child were killed in the attack, but implied the terrorist leader escaped with his life.
Deif has been targeted for assassination four times previously, including one attack in which he lost his legs and another in which he lost an eye.
