Jornal Do Brasilia - One million Gazans displaced as Israel readies for ground attack

Israel declared war on the Islamist group last Sunday, a day after waves of fighters broke through the heavily fortified border and shot, stabbed and burned to death more than 1,400, most of them civilians.

Seven days of relentless bombing targeting those who masterminded the attack have left more than 2,300 people dead, the majority ordinary Palestinians.

But even as Israel seeks to avenge the worst attack in its history, it faced a grave warning about the security implications of putting boots on the ground in the densely populated enclave.

"No one can guarantee the control of the situation and the non-expansion of the conflicts" if Israel sends its soldiers into Gaza, said Iran's foreign minister Hossein Amir-Abdollahian.

"Those who are interested in preventing the scope of war and crisis from expanding need to prevent the current barbaric attacks... against citizens and civilians in Gaza," he added.

Iran is Israel's number one enemy and as well as funding Hamas also backs Hezbollah in Lebanon to the north, where cross-border fire has intensified in the last week.

At least 10 people have now been killed in Lebanon and two in Israel, prompting Israel to shut the border area to civilians.

Iran has praised the Hamas attacks but insisted it was not involved. However the United States, which has sent two aircraft carriers to the eastern Mediterranean in a show of support for Israel, is wary.

In Washington, White House National Security Adviser Jake Sullivan said the United States feared an escalation, particularly the prospect of Iran becoming "directly engaged".

US Secretary of State Antony Blinken has in recent days toured Middle Eastern capitals in a frantic round of diplomacy to try to avert a wider crisis in the volatile region.

He is due back in Israel on Monday for further talks with Israeli leaders, the State Department said as he arrived in Cairo.

Blinken has appealed to China to use its influence in the region to ease tensions.

But on Sunday Foreign Minister Wang Yi said Israel's response had "gone beyond the scope of self-defence".

He called on Prime Minister Benjamin Netanyahu and his emergency government to "cease its collective punishment of the people of Gaza".

- Evacuations -

Israel has massed thousands of troops and heavy weaponry in the desert south of the country, waiting for the green light to go in to northern Gaza.

The army has told 1.1 million Palestinians in the north of the Gaza Strip -- nearly half of its 2.4-million population -- to head south to safety.

On the other side of the border, Israelis were moving to safer areas.

Military spokesmen Lieutenant Richard Hecht and Daniel Hagari said any ground offensive would be triggered by a "political decision".

Netanyahu visited frontline troops on Saturday, telling them "more is coming" but without specifying when any ground operation would start.

Hecht singled out Yahya Sinwar, the chief of Hamas in Gaza blamed for the October 7 attacks, calling him "a dead man walking".

Aid agencies, including the UN and ICRC, as well as foreign governments have repeatedly criticised Israel's request for Gazans to leave their homes -- and accused it of inflicting collective punishment on ordinary people.

The UN agency supporting Palestinian refugees said on Sunday that some one million people had already been displaced in the first week of the conflict.

"The number is likely to be higher as people continue to leave their homes," UNRWA director of communications Juliette Touma told AFP.

Palestinians carrying whatever belongings they can, in bags and suitcases, or packed onto three-wheeled motorbikes, battered cars, vans and even donkey carts have become a common sight in recent days.

But they have had to find shelter wherever they can in the increasingly crowded south of the Gaza Strip, including in the street and UN-run schools.

Israel had cut off water, fuel and food supplies to Gaza for the duration of the conflict. Local hospitals are becoming overwhelmed with increasing numbers of dead and injured.

The White House said on Sunday that Israel had turned water back on in the south.

But electricity outages threatens to cripple life-support systems, from sea water desalination plants to food refrigeration and hospital incubators.

In Rome, Pope Francis called for humanitarian corridors in Gaza and urged that "children, the sick, the elderly, women and all civilians should not fall victim to the conflict".

"There have already been so many deaths, please let's not shed any more innocent blood," he said, castigating "the diabolical force of hatred, terrorism and war".

Gazans are effectively trapped, with Israeli-controlled crossings closed and Egypt also having shut the Rafah border in the south.

Convoys of humanitarian aid are stacked up on the Egyptian side, witnesses told AFP.

- Hostages -

The mood in Israel has swung between collective grief, fury and a strong desire to punish Hamas, which Netanyahu has likened to the Islamic State group.

Public outrage has been fuelled by images and reports shared on social media of youths and families shot, stabbed, burnt and mutilated in the Hamas attack.

There are also deep fears about the safety of some 120 hostages being held in the Gaza Strip.

"We must bring them back home alive," said a tearful Yrat Zailer, the aunt of children aged nine months and four years who were abducted with their mother.

Israel pushed on with its evacuation of southern towns close to Gaza that were targeted in the Hamas attacks.

Packed buses were taking families to hotels in Jerusalem and the Red Sea resort city Eilat.

"It's hard, I'm crying," said Helen Afteker, 50, an evacue from the town of Sderot. "It's terrifying every time there's a warning, we have to leave. It's better for the children."

Planeloads of Israelis have returned from around the world to join the latest of the many wars in Israel's 75-year history.
