Israeli Prime Minister Benjamin Netanyahu’s office announced on Tuesday that the strike in Doha that killed five Hamas members was “a wholly independent Israeli operation.”

In its statement, the office emphasized:

“Israel initiated it, Israel conducted it, and Israel takes full responsibility.”

Among the dead is the son of Khalil al-Hayya, Hamas' leader for Gaza and top negotiator, the group's statement said. Also killed was the head of al-Hayya's office, said Suheil al-Hindi, a member of Hamas' political bureau, speaking to Al-Jazeera. The main target of the strike was reportedly al-Hayya, who Hamas said survived the attack.

"We confirm Israel's failure to assassinate its leaders in the negotiating delegation in Qatar," Hamas said in the statement.

Hamas previously denied that any of its members were killed in the precision strike.

An Israeli official has stated that there is no confirmation that senior Hamas figures were killed in the strike, adding "we're waiting."

Israel alerted the U.S. ahead of time, according to an Israeli official, a White House official and another person familiar with the matter. The White House official would not say if Washington provided Israel with approval for carrying out the strike, but another U.S. official said the American military did not participate.

he statement from Netanyahu’s office followed an unprecedented Israeli airstrike in Doha, Qatar, aimed at Hamas leaders reportedly gathered to discuss a U.S.-brokered ceasefire proposal. The operation — codenamed “Day of Judgment” — was the first known Israeli military action inside Qatari territory.

In a televised address, Netanyahu said the days when "terrorist" leaders were immune anywhere were over.

"The days are over when terror leaders can enjoy immunity of any kind ... I won't allow that kind of immunity to exist," he said.

Israel’s move drew sharp condemnation from Qatar, which called it a “cowardly criminal assault” and a violation of sovereignty and international law. The U.S. Embassy in Doha urged American citizens to shelter in place.

Qatar had served as a key mediator alongside Egypt and the U.S. in Gaza ceasefire and hostage negotiations. Its officials have since signaled that Doha may suspend mediation efforts “until further notice” following the breach.

While Israel insists the operation was fully self-directed, reports suggest prior consultations with Washington, highlighting the broader geopolitical stakes of the strike.
