Israel has carried out a strike targeting the senior leadership of Hamas in Qatar’s capital, Doha.

A Hamas official told the BBC that members of the Palestinian armed group’s negotiating team were targeted during a meeting. It was not clear whether any of them were killed, but photos showed a badly damaged building in the northern Katara district.

The Israeli military accused the Hamas leaders of being directly responsible for the 7 October 2023 attack on Israel and of orchestrating the ensuing war in Gaza.

Qatar strongly condemned what it called the “cowardly Israeli attack that targeted residential buildings housing several members of the political bureau of Hamas”.

“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,” a foreign ministry statement said.

The Gulf state – a key US ally in the region that is the location of a major American air base – has hosted the Hamas political bureau since 2012 and has served as a mediator in indirect negotiations between the group and Israel.

UN Secretary General António Guterres also condemned the strike, saying it was a “flagrant violation” of Qatar’s sovereignty.

Israeli Prime Minister Benjamin Netanyahu’s office stressed that what it called the “action against the top terrorist chiefs” of Hamas was a “a wholly independent Israeli operation”.

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

A senior Israeli official told Israeli media that the Hamas members targeted included Khalil al-Hayya, the chief negotiator and exiled Gaza leader, and Zaher Jabarin, the exiled West Bank leader.

“We are awaiting the results of the strike. There is a consensus among the political and security leadership,” the official added.

On Monday, Israeli Defence Minister Israel Katz had warned Hamas leaders living abroad that they faced “annihilation” and Gaza would be destroyed if the group did not release its hostages and lay down its arms.

The Israeli military launched a campaign in Gaza in response to the Hamas-led attack on southern Israel on 7 October 2023, in which about 1,200 people were killed and 251 others were taken hostage.

At least 64,605 people have been killed in Israeli attacks in Gaza since then, according to the territory’s Hamas-run health ministry.
