A diplomatic source familiar with the matter told Al Jazeera that Israeli Prime Minister Benjamin Netanyahu – wanted by the International Criminal Court – apologized for violating the sovereignty of the State of Qatar and the killing of a Qatari security officer in the attack on Doha on September 9.

The source explained that the apology came during a joint call received by the Qatari Prime Minister and Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani from Netanyahu and U.S. President Donald Trump during their meeting at the White House on Monday.

The source pointed out that the call was initiated by Trump and that the discussions involved all three parties.

The Israeli Broadcasting Corporation quoted a source saying that Qatar demanded Netanyahu’s apology as a condition for continuing its participation in the negotiations, and also quoted a source saying that Netanyahu’s government ministers were not informed about the apology to Qatar.

Israel faced widespread Arab and international condemnation after bombing the Qatari capital, targeting residential headquarters of the leadership delegation of the Islamic Resistance Movement (Hamas) while they were gathered to discuss Trump’s proposal for a ceasefire in Gaza.

Hamas leaders survived the attack, while 5 Hamas members and a member of the Qatari Internal Security Force were killed.

Qatar – which acts as a mediator to end the genocide war in Gaza for about two years – described the Israeli attack as a treacherous aggression and state terrorism, affirming that it violates the principle of mediation itself, and pledged to take all measures to protect its security and territorial integrity.
