Hamas accused Israeli Prime Minister Benjamin Netanyahu of a "blatant violation" of the October 2025 ceasefire after he ordered the army to seize more territory in Gaza.
Mr Netanyahu has ordered the military to take control of more territory in Gaza, flouting the terms of a fragile ceasefire that took effect in October.
He said the military had controlled 50% of the Palestinian territory under the terms of the ceasefire, then advanced to take over 60%. "My directive is to move to... 70%," he said.
"We're squeezing them from all (sides). We'll deal with what's left afterwards," he added.
Hamas political bureau member Bassem Naim described this as a "blatant violation of all agreements, as is their usual practice", adding that it will take place "while the killing and starvation continue".
Hamas spokesman, Hazem Qassem, also condemned the "complete silence" of US President Donald Trump's Board of Peace and its high representative for Gaza, Nickolay Mladenov, on the topic.
"Failing to condemn Israel's expansionist policies and forced displacement plans raises serious questions about the extent of the sponsoring parties' commitment to obliging Israel to adhere to its obligations" under the ceasefire deal," Mr Qassem said in a separate statement.
The first phase of the truce that started in October 2025 saw the last hostages seized in Hamas's 7 October 2023 attacks on Israel, which triggered the war in Gaza, released in exchange for Palestinians detained by Israel.
The transition to the second phase, which was supposed to involve Hamas's disarmament and a gradual withdrawal of the Israeli army, has been stalled for months.
Under the terms of the ceasefire, Israeli forces were to pull back behind a so-called "yellow line", a demarcation between the area under Hamas control and that held by the Israeli army.
Mr Netanyahu announced on 15 May that the Israeli army had expanded its grip on Gaza.
"There were those who said: get out, get out. We did not get out. Today we control... how much? 60%. Tomorrow we shall see," he said at the time.
Gaza remains gripped by daily violence, with both the Israeli military and Hamas accusing one another of violating the truce in effect since 10 October.
More children will suffer due to new plan, says UN
The UN warned that the new Israeli plan to take control of 70% of Gaza will increase suffering among children already hit by the impacts of severe overcrowding.
The United Nations children's agency UNICEF warned that this would deepen the health crisis among children in the war-ravaged territory, suffering from acute lack of food, water and hygiene.
Israel controls the flow of aid into the territory along with all entry points into Gaza, which has been under an Israeli blockade since 2007.
Even before Hamas's 7 October 2023 attacks inside Israel triggered the war in Gaza, the territory was already very densely populated.
Now "people have been crammed into around 40% of the space", UNICEF spokesman Salim Oweis told reporters in Geneva, speaking from Gaza.
People there were left "sheltering among broken buildings, rubble and mounting solid waste", he said, adding "there is no accessible space left to clear" the waste.
"The effects of this are now widely apparent: children with respiratory infections, acute watery diarrhoea, and more than half of all households reporting skin diseases."
