GAZA CITY (CNN) — Israel’s fourth day of attacks in Gaza sent the Palestinian death toll to more than 375 as the Jewish state’s prime minister warned Tuesday that the air offensive marked only the beginning, according to officials.
“We are currently at the first stage of the operation,” Prime Minister Ehud Olmert told President Shimon Peres during a morning briefing, officials said.

Olmert’s summation came a day after Defense Minister Ehud Barak told Israel’s parliament that the campaign launched Saturday marked an “all-out war” against Hamas, the Islamic militant group that rules Gaza.
However, an official in the Defense Ministry said Barak would consider a proposal for a two-day truce to allow humanitarian aid into Gaza, a proposal raised by French Foreign Minister Bernard Kouchner.
The international community also stepped up its involvement Tuesday, with Kouchner calling Olmert about the proposal, French Foreign Ministry sources said.

The United Nations has called for both sides to end the violence, and U.N. Secretary General Ban Ki-moon has roundly condemned both sides: Hamas for the rocket fire and Israel for its “excessive use of force” in retaliating.
The Israeli military says it is targeting only Hamas militants, which it says are responsible for a recent barrage of rocket fire into southern Israel.
“They are committed to our destruction,” Former Prime Minister Benjamin Netanyahu said of Hamas. “They’re firing missiles at our civilians. They’re hiding behind their civilians. That’s a double war crime right there.” See world leaders’ reactions to Gaza invasion »
Palestinian parliament member Mustafa Barghouti, however, has called the raids a “war on the Palestinian people” and said the incursion is politically motivated.

Israel has allowed dozens of trucks carrying relief supplies into Gaza. Also, the Rafah border crossing to Egypt was opened temporarily Tuesday to allow aid workers and medical supplies into Gaza and to transport injured Palestinians to hospitals in Al Arish, about 19 miles from the border, Egyptian journalist Shahira Amin said.
Doctors in Al Arish said they were treating 36 wounded Palestinians, at least six of whom were critically injured and being transferred to a hospital in Cairo, Egypt, for treatment. More patients were expected to arrive Tuesday, the doctors said.
At least one hospital is severely lacking in supplies, a doctor who works there told CNN.
“There is nothing you can give to the patients,” said Dr. Mahmud El Khzndar, who works in the emergency room of Gaza City’s Shesaa Hospital. “There is no supply for the hospital, no narcotics for severely crushed people, for injured people. These people are dying in front of our eyes and between our hands.”
The escalating violence in Gaza triggered protests this week across the globe, from Greece, Britain and Lebanon to the United States.
A crowd of several hundred people gathered outside the State Department Tuesday afternoon in Washington, chanting “Stop the killing! Stop the war!” and “Free Palestine” before marching toward the White House.
