As Operation Pillar of Defense entered its fifth day, Prime Minister Benjamin Netanyahu spoke over the weekend with U.S. President Barack Obama and German Chancellor Angela Merkel, saying he had told both that he is prepared for a comprehensive cease-fire if the rocket fire from Gaza will stop.

Jerusalem residents received their first taste of rocket warnings over the weekend as terror groups fired more missiles on the south and at Tel Aviv, and the Israel Defense Forces continued to prepare for a possible ground invasion as Pillar of Defense ended its fourth day.

After a rocket was fired at the Tel Aviv area on Friday, the army deployed a fifth, new, Iron Dome antimissile battery in the region on Saturday morning. Within two hours, the system considered more advanced than the previous four because of its more sophisticated radar system intercepted a Fajr-5 rocket fired at the city.

Over 60 rockets were fired at Israel on Saturday. While many of them were intercepted by the Iron Dome system, including rockets aimed at Sderot, Netivot, Ashdod, and Be'er Sheva, a 10-story building was hit in Ashdod at midday and a car was damaged during a barrage of rockets on that city.
