El-Sisi made these remarks in a speech he delivered before the Emergency Arab-Islamic Summit in Doha.
He said the world must recognise that Israel's policies brazenly defy international laws, established norms, and humanitarian values.
The Egyptian president warned that Israel's reckless and increasingly destabilising conduct gravely risks broadening the scope of the conflict and plunging the region into an uncontrollable spiral of escalation.
"This is a situation that is utterly unacceptable and cannot be tolerated," he stated.
El-Sisi stressed that Israel seeks to turn the region into a lawless arena for aggression, posing a grave threat to regional stability. He added that Israeli practices undermine international peace and security and constitute a dangerous threat to the established global order.
Addressing the Israeli people, the Egyptian president warned that the unfolding events risk undermining the future of peace in ways that threaten Israelis' security, erode opportunities for any new peace agreements, and even abort existing peace accords with the nations of the region.
He noted that consequences will be severe and that the region could revert to a state of conflict, thus wasting the historic efforts to build peace and the fruits they have yielded.
This is a price we will all pay, without exception, El-Sisi stressed. "Therefore, do not allow the peace efforts of your predecessors to come to nought, for a time will come when remorse is utterly futile," he said.
Unwavering support for Qatar
During his speech, the Egyptian president affirmed Cairo's full solidarity with Doha amid the recent Israeli aggression on Qatari airspace and territories. He expressed Egypt's rejection of any violations of states' sovereignty or threat to their security and stability.
El-Sisi expressed, in the strongest and most unequivocal terms, Egypt's condemnation of this Israeli aggression against the sovereignty and security of a fellow Arab nation.
"This act of aggression irrefutably demonstrates that Israel's actions have abandoned all political or military rationale and have brazenly crossed every red line," the Egyptian president said.
Moreover, El-Sisi stated that the Israeli attack on Qatar amounts to an outrageous violation of international law and the UN Charter and establishes a perilous precedent that undermines Arab and Islamic national security.
"We will not accept any attack on the sovereignty of our countries, and we will not allow peace efforts to be thwarted," he stressed.
He highlighted Qatar's pivotal role, alongside Egypt and the US, in mediating a ceasefire in Gaza and bringing an end to the war and unprecedented suffering endured by the Palestinian people.
The Egyptian president stressed that Israel must comprehend that its security and safety will not be achieved through policies of force and aggression but through unwavering commitment to international law and full respect for the sovereignty of Arab and Islamic nations.
"The sovereignty of these nations shall not be infringed upon under any pretext. These are utterly non-negotiable principles," El-Sisi affirmed.
He noted that Israel's persistent violations will only breed further tension and instability for the entire region, with dire consequences for international security.
The Egyptian president said Egypt continues to urge the international community to uphold its moral and legal responsibilities to prevent the recurrence of such assaults and end Israel's brutal and indiscriminate war on Gaza.
He stressed that these responsibilities necessitate holding accountable those responsible for the flagrant violations and dismantling the entrenched culture of impunity that has long shielded Israeli practices.
Arab-Islamic unity
During his speech, El-Sisi underscored the importance of Arab-Islamic unity as a fundamental pillar for addressing regional challenges and ensuring we do not slide into further chaos and conflict.
"The unchecked Israeli recklessness and its increasingly inflated arrogance require us, as leaders of the Arab and Islamic worlds, to act collectively to establish foundations and principles that genuinely reflect our shared vision and interests," he said.
He underscored the importance of establishing an Arab-Islamic mechanism for coordination and cooperation amidst the significant security, political, and economic challenges in the region.
"At this critical historical juncture, it has become imperative for us to establish an Arab-Islamic mechanism for coordination and cooperation to enable us all to confront the major security, political, and economic challenges surrounding us," he said.
El-Sisi noted that establishing such a mechanism represents the way to strengthen the Arab-Islamic nations' front and ability to confront current challenges and take the necessary steps to safeguard their security and shared interests.
The Egyptian president also pointed to the recent adoption by the Arab League Council of "The Common Vision for Security and Cooperation in the Region" resolution, which provides a vital foundation for forging a unified Arab-Islamic consensus.
He noted that this consensus should be based on a governing framework for regional security and cooperation that also establishes implementation mechanisms to address the delicate situation Arab and Islamic nations face.
"This framework shall prevent any party from asserting regional dominance or imposing unilateral security arrangements that would undermine the security and stability of Arab and Islamic nations," El-Sisi said.
Additionally, the Egyptian president affirmed that Arab and Islamic nations will stand united in defending their rights, most importantly the right of the Palestinian people to establish their independent state and live in freedom, dignity, and security.
"Our positions must change the enemy's perception of us, so it can see that the geography of any Arab country extends from the Ocean to the Gulf and its umbrella is wide enough for all Islamic and peace-loving countries," he said.
For this perception to change, the Egyptian president urged the adoption of strong decisions and recommendations, and their implementation with sincerity and honest intentions to deter every transgressor and adventurer.
"Egypt fully supports all earnest efforts toward a just peace and the security and stability of the Arab and Islamic worlds," El-Sisi said.
Israeli aggression on Gaza
Addressing the Israeli war on Gaza, El-Sisi reaffirmed Egypt's full rejection of the targeting of civilians and the policy of collective punishment and starvation practised by Israel against the Palestinian people.
"I stress here that military solutions, the thwarting of mediation efforts, and continuing to impose a fait accompli through brute force will not achieve security for any party," he said.
El-Sisi noted that it has now become clear that Israel's aggressive approach carries a deliberate intent to sabotage all efforts toward de-escalation and reaching a deal that would secure a permanent ceasefire and ensure the release of captives and detainees.
"This conduct indisputably reveals the profound absence of political will on Israel's part to engage in any earnest efforts toward establishing a just and enduring peace in the region," he said.
The Egyptian president stressed that Egypt will continue its steadfast support for the resoluteness of the Palestinian people as they cling to their land, identity, and legitimate rights, in accordance with international law.
"Egypt will also confront any attempt to undermine these inalienable rights," El-Sisi added.
He said that Cairo will confront attempts such as settlement activities, land annexation, displacement, or other forms of uprooting Palestinians from their land.
The Egyptian president reiterated Egypt's outright rejection of any proposals to displace Palestinians from their land. "Such proposals have no legal or moral foundation and will only expand the scope of the conflict, which would destabilise the entire region," he said.
"The time has come to seriously and decisively address the Palestinian cause, as it is vital to the region's stability," the Egyptian president stressed, describing the Palestinian issue as the central cause of the Arab and Islamic worlds.
He affirmed that a just and comprehensive solution to the Palestinian cause should be based on ending the occupation and establishing an independent Palestinian state along 4 June, 1967 borders, with East Jerusalem as its capital.
El-Sisi further stated that the upcoming UN two-state solution conference would represent a pivotal milestone on the path to achieving a just and sustainable solution to the Palestinian cause, particularly through the recognition of the Palestinian state.
"I reiterate the call for the immediate recognition of the Palestinian state by all states that have not yet taken this step, as this is the only way to preserve the two-state solution," he stressed.
