US officials knew about the attack on the Hamas leadership in Doha, Qatar, and gave the green light for the operation, Israeli officials told The Jerusalem Post on Tuesday.
However, a US official told the Post that no advance warning was given, nor was any approval obtained.
"Today's action against the top terrorist chieftains of Hamas was a wholly independent Israeli operation. Israel initiated it, Israel conducted it, and Israel takes full responsibility," the Prime Minister's Office said in a statement.
"Hamas received the new proposal from the Qataris, which we [Israel] obtained from Witkoff last week in Paris. The prime minister met with the Hamas leadership yesterday, and they decided to meet again today to discuss the proposal, arriving from Turkey," a diplomatic source told the Post.
"As it happened before, the Israelis undermined hopes for peace, further prolonging the war and complicating efforts to bring back the hostages," Qatar responded.
Qatar strongly condemns 'cowardly Israeli attack'
Qatar officials announced on Tuesday that all mediation efforts regarding a hostage deal have been halted immediately, following the Israeli strike on Doha.
"The State of Qatar strongly condemns the cowardly Israeli attack that targeted residential buildings housing several members of the Political Bureau of Hamas in the Qatari capital, Doha," said Majed al-Ansari, spokesperson of the Qatari Foreign Ministry.
"This criminal assault constitutes a blatant violation of all international laws and norms, and poses a serious threat to the security and safety of Qataris and residents in Qatar," he added.
"While the State of Qatar strongly condemns this assault, it confirms that it will not tolerate this reckless Israeli behavior and the ongoing disruption of regional security, nor any act that targets its security and sovereignty."
UAE, Saudi Arabia, Gulf states condemn the attack on Qatar
"The Israeli attack on Doha was blatant and cowardly," the United Arab Emirates Foreign Minister, Abdullah bin Zayed, Reuters reported.
He also published a comment on X where he said: "Full solidarity with our dear Qatar."
Saudi Arabia's Foreign Ministry also issued a statement condemning the attack on Doha. "The Kingdom of Saudi Arabia condemns and denounces in the strongest terms the brutal Israeli aggression and the flagrant violation of the sovereignty of the sisterly State of Qatar," they said.
The statement also warned against "Israel's persistence in its criminal transgressions and its blatant violation of the principles of international law and all international norms."
Saudi Crown Prince Mohammed bin Salman said on Wednesday that the kingdom rejected and condemned Israel's "assaults" in the region, the latest being Tuesday's attack on Doha.
"The brutal aggression against the sisterly state of Qatar requires Arab, Islamic and international action," he said in a televised address.
Kuwait's Foreign Ministry also called out the attack with a statement that qualifies it as a "brutal aggression at the hands of the unjust Israeli forces."
"The Ministry emphasizes that this brutal Israeli aggression constitutes a flagrant violation of all international laws and a serious threat to the security and stability of the region, and a direct undermining of international peace and security," read the statement.
Oman's Foreign Ministry stated that the attack was a "criminal and treacherous political assassination, that is in flagrant violation of international law and the sovereignty of Qatar."
Jordan and Egypt fear strike may lead to escalation
Jordan's King Abdullah II called the Qatari Emir, Sheikh Tamim bin Hamad Al Thani, after the strike on Doha, explaining that "Qatar’s security is integral to Jordan’s security."
The Jordanian foreign minister, Ayman Safadi, said on X that Jordan "stands in full solidarity with Qatar against the Israeli aggression."
"The whole international community must condemn this aggression on Qatar. It is time the world realized the horrific consequences of continuing to allow Israel to act above the law and commit crimes with impunity," he added.
The statement concluded asking for the UN Security Council to "end the criminal and destructive acts of a rogue Israeli government."
Egypt also condemned the attack, claiming that "it sets a dangerous precedent." "The escalation harms global efforts to reduce tensions in the region," said an official statement.
