“No country on earth would tolerate missiles raining down” on its population, he said.
In his conversations with Mr. Obama and European leaders, Mr. Netanyahu urged them to intercede with Egyptian President Mohammed Morsi and have him put pressure on Hamas.
Turkish Prime Minister Recep Tayyip Erdogan has joined Mr. Morsi in his talks in Cairo with Hamas representatives.
“We have mobilized forces to end the threat, and we may have to be even more aggressive than we have been,” he said.
At least five missile strikes were fired at Tel Aviv, but the rockets either failed to reach the coastal city or were shot down by Israel’s Iron Dome anti-missile defense. One rocket was fired at Jerusalem on Friday evening, just as residents were preparing for their Sabbath eve meal, but it exploded in an open area away from the city.
The Israeli air force has hit more than 1,000 targets since Wednesday, attacking arsenals, launching pads, tunnels and other elements in the military infrastructure of Hamas, Islamic Jihad and other terrorist organizations in the Gaza Strip.
The air force destroyed a Hamas building used for constructing unmanned drone aircraft designed to attack Israeli cities, a military spokesman said.
Using precision weapons in order to avoid “collateral damage” to civilians, the air force has dropped 200 tons of bombs daily in the densely built-up Palestinian enclave.
Israeli army intelligence also managed to take electronic control of the Hamas radio station. It broadcast a warning in Arabic for Gaza citizens to distance themselves from Hamas rocket sites and other military targets frequently located in residential areas.
Israeli planes attacking before dawn Sunday also destroyed the office of Hamas Prime Minister Ismail Haniyeh and the Interior Ministry. Both offices were empty. Gaza’s civilian infrastructure has not been targeted, although the bombing has caused power failures.
The Gaza militants have fired 1,000 rockets at Israel since the beginning of the conflict, but close to 90 percent of those heading for built-up areas were intercepted by Israel’s anti-missile system.
Most of the rest either landed in open areas or failed to travel beyond Gaza’s border. A few dozen rockets landed in Israeli towns, killing three people and wounding several dozen.
