Israeli forces are still trying to defeat the last groups of militants holed up in several towns since Hamas launched its unprecedented attack on Saturday.
A “complete siege” of the Gaza Strip – leaving the territory with no food, electricity or fuel – has been ordered by Israel.
Israeli defence minister Yoav Gallant said Israel was “battling beastly people” and was conducting itself as such, after Hamas launched a surprise attack from Gaza on Sunday.
The Israeli infrastructure minister Israel Katz said he had ordered the water supply between Israel and Gaza to be shut off immediately.
It comes as a “huge rocket barrage” out of Gaza hit central Israel late on Monday morning.

Israeli forces are currently fighting Hamas in two locations inside Israel, after the country formally declared war on the militant group.
Around 300,000 reservists have been called up by the Israeli military.
Doron Spielman, a spokesperson for the Israel Defence Forces (IDF), said, there is still active fighting with Hamas militants “constantly trying to cross over” the border from Gaza.
This is despite Israeli troops having regained control in some areas of southern Israel.
“They keep stringing to the border and we expect this to continue because there’s a massive number of jihadis that have been trained to do this,” he told NBC.
Other key developments include:
• Nearly 1,200 have died and thousands are wounded on both sides;
• Hundreds of Israelis are being held hostage by Hamas, including women, children and the elderly;
• Israeli captives and their captors have been killed in airstrikes since the weekend, according to Hamas;
• Israeli civilians have been gunned down in towns, along roads and at a techno music festival being held in the desert near Gaza;
• Rishi Sunak is chairing a COBRA emergency response meeting;
• More than 123,000 people have been displaced in Gaza, UN says.
At least 700 people have reportedly been killed in Israel and 560 have died in Gaza as Israel retaliated with airstrikes in an operation which has been dubbed “Swords of Iron”.
On Monday, Hamas’s armed wing claimed four Israeli captives and their Hamas captors have been killed in strikes since the beginning of the attack.
An Israeli air strike also killed 19 people, including women and children, said Talat Barhoum, a doctor at the local Al Najjar Hospital in Gaza.
Inside the Gaza Strip, more than 1,000 targets had been hit, the IDF said earlier, including airstrikes that levelled much of the town of Beit Hanoun in the northeast corner.
Meanwhile, the IDF said on Monday that it thought the situation would be in “a better place”.
Mr Spielman said Hamas fighters have “embedded themselves” in Israel, with one individual coming out of hiding and shooting in one community.
