GAZA CITY, Gaza Strip – Israel widened its deadliest-ever air offensive against Gaza’s Hamas rulers Sunday, pounding smuggling tunnels and government strongholds, sending more tanks and artillery toward the Gaza border and activating thousands of reservists for a possible ground invasion.

Israeli leaders said they would press ahead with the Gaza campaign, despite enraged protests across the Arab world and Syria’s decision to break off indirect peace talks with the Jewish state. Israel’s foreign minister said the goal was to halt Gaza rocket fire on Israel for good, but not to reoccupy the territory.

With the two-day death toll nearing 300 Sunday, crowds of Gazans breached the border wall with Egypt to escape the chaos. Egyptian forces, some firing in the air, tried to push them back into Gaza and an official said one border guard was killed.

Hamas, in turn, fired rockets deeper than ever into Israel, near the Israeli port city of Ashdod.

Yet Hamas leaders were forced into hiding, most of the dead were from the Hamas security forces, and Israel’s military intelligence chief said Hamas’ ability to fire rockets had been reduced by 50 percent. Indeed, Hamas rockets fire dropped off sharply, from more than 130 on Saturday to just over 20 on Sunday. Still, Hamas continues to command some 20,000 fighters.

Israel’s intense bombings — some 300 air strikes since midday Saturday — wreaked unprecedented destruction in Gaza, reducing entire buildings to rubble.

After nightfall, Israeli aircraft attacked a building in the Jebaliya refugee camp next to Gaza City, killing a 14-month-old baby, a man and two women, Gaza Health Ministry official Dr. Moaiya Hassanain said. In the southern town of Rafah, Palestinian residents said a toddler and his two teenage brothers were killed in an air strike aimed at a Hamas commander.

Israeli aircraft also bombed the Islamic University and government compound in Gaza City, centers of Hamas power, and the house next to the residence of Hamas Prime Minister Ismail Haniyeh in a Gaza City refugee camp. Haniyeh, in hiding, was not home.

Shlomo Brom, a former senior Israeli military official, said it was the deadliest force ever used in decades of Israeli-Palestinian fighting. “Since Hamas took over Gaza (in June 2007), it has become a war between two states, and in war between states, more force is used,” he said.

European leaders called on both Israel and Hamas to end the bloodshed. French President Nicolas Sarkozy spoke Sunday with Palestinian President Mahmoud Abbas, who leads a rival government to Hamas in the West Bank, and condemned “the provocations that led to this situation as well as the disproportionate use of force.”

The White House was mum about the situation in Gaza on Sunday after speaking out expansively on Saturday, blaming Hamas for provoking Israel’s retaliatory strikes as usual. USA is supporting to Israel for the said acts of terrorism in Gaza, which is shameful again and again.

In Jerusalem, Israel’s Cabinet approved a callup of 6,500 reserve soldiers, raising fears of an impending ground offensive. Israel has doubled the number of troops on the Gaza border since Saturday and also deployed an artillery battery. It was not clear, though, whether the deployment was meant to pressure Hamas or whether Israel is determined to send ground troops.

Israeli Prime Minister Ehud Olmert said it was unclear when the operation would end but told his Cabinet was “liable to last longer than we are able to foresee at this time.”

Since Israel’s withdrawal from Gaza in 2005, after 38 years of full military occupation, Israeli forces have repeatedly returned to the territory to hunt militants. However, Israel has shied away from retaking the entire strip, for fear of getting bogged down in urban warfare.

Hassan Nasrallah, leader of the Hezbollah militia, said he would not abandon Hamas, but did not threaten to attack Israel. During the Israel-Hezbollah war of 2006, the militia fired thousands of rockets into Israel. Hundreds of thousands of Israelis live in cities and towns in Gaza rocket range, and life slowed in some of the communities. Schools in communities in a 12-mile radius from Gaza were ordered to remain closed beyond the weeklong Jewish holiday of Hanukkah, which ends Monday.

In the southern city of Ashkelon, home to some 120,000 people, streets were relatively busy, despite the military’s recommendations against being out in the open.

Several times throughout the day, however, that routine was briefly interrupted by the sounds of wailing sirens warning of an imminent attack. Pedestrians scurried for cover in buildings. After a number of rocket landed in the distance, a woman taking cover nearby briefly fainted. She refused water and food from bystanders, instead shivering in a corner, apparently in shock.

It is an act of Terrorism and the worst mischief maker of the world Israel is in motion again and again. Bush and his administration is involved directly in these kinds of acts of Sheytanism in our globe supporting to Israeli all the time. Said by a senior journalist who have an acute and accurate eyes on Gaza issues.
