- More than 10,000 wounded in Gaza
- One million Gazans displaced
- Troops prepare to move on shattered Gaza
In the West Bank, the Israeli occupation shot a child dead in southern Nablus to take the total of martyrs to 56, while the number of the wounded jumped to over 1,200.
The Palestinian News Agency (WAFA) quoted medical sources as saying that more than 50 families were completely removed from the civil registry, as a result of the occupation's massacres by bombing homes in several cities and camps in the Gaza Strip.
More than one million people have been forced from their homes in the northern Gaza Strip since Israel began its bombardment against Hamas, the UN said, warning of dire conditions on the ground.
The Arab League and African Union warned the invasion could lead to "a genocide of unprecedented proportions
As Israeli troops prepared to move into the Gaza Strip in pursuit of Hamas militants, Prime Minister Benjamin Netanyahu vowed Sunday to "demolish Hamas".
Israel has urged exhausted Gazans to evacuate south, which hundreds of thousands have already done in the besieged enclave that is home to more than 2mn people. Hamas, which runs Gaza, has told people to ignore Israel's message.
Inside Gaza's narrow and crowded streets, conditions were deteriorating as deaths from Israeli air strikes rose.
With fears of the conflict spilling further, US Secretary of State Antony Blinken continued his tour of Middle East states, seeking to prevent escalation and secure the release of 155 hostages Israel says were taken by Hamas back into Gaza.
Arab leaders stressed the need to protect Gaza civilians.
"The reaction went beyond the right to self-defence, turning into collective punishment," said Egypt's President Abdel Fattah al-Sisi of Israel's retaliatory strikes.
Clashes on Israel's border with Lebanon, the deadliest since 2006, have underscored the dangers of regional spillover.
Hamas' armed wing Al Qassam Brigades said it fired 20 rockets from Lebanon at two Israeli settlements while Lebanon's Hezbollah militia said it fired missiles at Israeli barracks in Hanita and had inflicted casualties.
Israel said it was striking Lebanon in retaliation.
Iran, which backs both Hamas and Hezbollah, warned Israel of escalation if it kept attacking Palestinians.
"If the Zionist aggressions do not stop, the hands of all parties in the region are on the trigger," said Foreign Minister Hossein Amir-Abdollahian, adding that Tehran could not simply stay an observer.
Gaza hospitals are running short of supplies and struggling to cope with the numbers of wounded.
The Israeli military said some 600,000 Gazans had left the northern half of the territory, which includes Gaza City's more than 1mn residents.
The events are reminding Palestinians of the "Nakba," or "catastrophe," when many were forced from their homes during the 1948 war that accompanied Israel's creation.
