Reading this from BBC:
On Monday, Israel declared a "complete siege" on the territory, saying electricity, food, fuel and water would be cut off.
Is this a war crime or illegal in any way under international laws?

Yes, completely cutting off food and water is a war crime. For example, we have the following quote by John Kerry, then US foreign secretary:
People are dying; children are suffering not as a result of an accident of war, but as the consequence of an intentional tactic – surrender or starve. And that tactic is directly contrary to the law of war.
Or by Ban Ki-Moon, then Secretary General of the UN:
Let me be clear: The use of starvation as a weapon of war is a war crime.
[Both were said regarding a siege taking place as part of the Syrian civil war.]
If rather than completely cutting off food the IDF would insitute a comprehensive inspection regime which makes smuggling in military supplies almost impossible, but inadvertently also limit throughput so much that no enough food reaches Gaza, the situation would be more complicated to judge.
for the specific purpose of denying them for their sustenance value to the civilian population or to the adverse Party,*
– Italian Philosophers 4 Monica Oct 12 '23 at 16:15If Hamas are using those supplies as well, it is no longer a war crime.
– Questor Oct 13 '23 at 16:25I am surprised that none of the answers so far cite actual international law (treaties). From the Additional Protocols of the Geneva Conventions, article 54:
Starvation of civilians as a method of warfare is prohibited.
It is prohibited to attack, destroy, remove or render useless objects indispensable to the survival of the civilian population, such as foodstuffs, agricultural areas for the production of foodstuffs, crops, livestock, drinking water installations and supplies and irrigation works, for the specific purpose of denying them for their sustenance value to the civilian population or to the adverse Party, whatever the motive, whether in order to starve out civilians, to cause them to move away, or for any other motive.
The prohibitions in paragraph 2 shall not apply to such of the objects covered by it as are used by an adverse Party:
(a) as sustenance solely for the members of its armed forces; or
(b) if not as sustenance, then in direct support of military action, provided, however, that in no event shall actions against these objects be taken which may be expected to leave the civilian population with such inadequate food or water as to cause its starvation or force its movement.
These objects shall not be made the object of reprisals.
In recognition of the vital requirements of any Party to the conflict in the defence of its national territory against invasion, derogation from the prohibitions contained in paragraph 2 may be made by a Party to the conflict within such territory under its own control where required by imperative military necessity.
At least one source notes that starvation of citizens is actually only prohibited “as a method of warfare”:
Less clear is whether the prohibition only relates to situations where the belligerent resorting to this method of warfare has the purpose of starving the civilian population; or whether it also covers situations where, although not the purpose of a particular course of action, the starvation of the civilian population is its foreseeable consequence.
I'm not a lawyer, but the implication of paragraph 3(b) seems to be that cutting off food and water would be prohibited, though cutting off electricity would apparently be acceptable.
User @CDJB notes that Israel is not a party to Protocol I, which this article comes from. (source) So Israel is not bound by treaty to honor this article.
Not that this is going to stop the comments, but: the purpose of this answer is to respond to the OP, not to take a position on the conflict.
As hinted in comments, the Israeli declaration (& actions) has/have already elicited protest from a UN commissioner, as France24 streamed:

Total siege of Gaza 'prohibited' under international law, says UN rights chief
Israel's total siege of the Gaza Strip is banned under international law, said the United Nations human rights chief.
"The imposition of sieges that endanger the lives of civilians by depriving them of goods essential for their survival is prohibited under international humanitarian law," Volker Turk said in a statement.
Citing information gathered by his office, Turk said Israeli air operations have struck residential buildings, including large tower blocks, as well as schools and UN buildings across Gaza, resulting in civilian casualties.
"International humanitarian law is clear: the obligation to take constant care to spare the civilian population and civilian objects remains applicable throughout the attacks," said Turk.
Tom Dannenbaum, a professor at the Fletcher School at Tufts University, has written an article about "siege starvation" in this particular context.1 He establishes the situation as follows:
On Monday [Oct. 9, 2023 -Peter], Minister of Defense Yoav Gallant announced, “I have ordered a complete siege on the Gaza Strip. There will be no electricity, no food, no fuel, everything is closed.”[...]
Reports indicate that Israeli Air Force strikes at the Rafah crossing and Israeli government warnings to Egypt not to allow aid in are preventing the delivery of essentials through the only land border not controlled by Israel.
His legal assessment of this announcement is:
This order commands the starvation of civilians as a method of warfare, which is a violation of international humanitarian law and a war crime (ICC Statute, article 8(2)(b)(xxv)). It may also satisfy the legal threshold for the crime against humanity of inhumane acts (7(1)(K)) and, depending on what happens from here, other crimes against humanity, such as those relating to killing (murder and extermination) (7(1)(a-b)).
The question whether the ICC has jurisdiction over the Gaza Strip was answered by the court itself in 2021:
FOR THESE REASONS, THE CHAMBER HEREBY
FINDS that Palestine is a State Party to the Statute;
[...]
FINDS, by majority, Judge Kovács dissenting, that the Court’s territorial jurisdiction in the Situation in Palestine extends to the territories occupied by Israel since 1967, namely Gaza and the West Bank, including East Jerusalem.
A Q&A document regarding that decision is available on the court's site.
Last not least, an official statement was issued by the UN High Commissioner for Human Rights, Volker Türk:
The imposition of sieges that endanger the lives of civilians by depriving them of goods essential for their survival is prohibited under international humanitarian law.
1 A more technical article by Dannenbaum from 2019 can be found here. Siege starvation was not part of the original Geneva Conventions and was added as an amendment to the Rome Statute of the ICC.
There is a concept of the Doctricne of necessary defence in the international law. It is allowed by the UN's International Law Commission (ILC) to be used by a state facing "grave and imminent peril".
Isreael may potentially claim that they are enough under "grave and imminent peril" after Hamas have killed thousands of civilians in they initial attack.
There are, however, some statements within this concept that the opposing side may use, like " the State has contributed to the situation of necessity" (Gaza side argues Israel contributed a lot) and "Actions taken were the only way to safeguard an essential interest from grave and impending danger" (how much is now needed to prevent the further Hamas attacks, it is also not very obvious).
One important factor omitted from this discussion:
"Gaza has its own agricultural industry". They even export quite a lot of their produce. See link: https://gaza-palestine.com/agriculture-in-gaza-strip/#:~:text=Gaza%20is%20famous%20for%20growing,%2C%20watermelons%2C%20melons%2C%20tomatoes.
Quoted from the link: "Gaza is famous for growing and exporting flowers, growing crops such as barley, wheat, and cotton and exporting them to the world. There are also many citrus fruits that are grown, such as oranges, lemons, potatoes, grapes, cucumbers, figs, strawberries, watermelons, melons, tomatoes."
So cutting off food supply from the outside would not definitely result in the death by starvation of all Gazans.
