Abu Obeida, the spokesman for Hamas's armed wing, has been killed in an air strike in Gaza City, Israel has said.
Israel's Defence Minister Israel Katz congratulated the Israel Defense Forces (IDF) and Israel's security agency, Shin Bet, for the flawless execution in a post on X.
He gave no detail on the time or location of the operation, but the IDF earlier said its aircraft attacked a key terrorist in the al-Rimal neighbourhood on Saturday, prompting reports in Israeli media that Obeida had been the target.
Hamas has not confirmed his death. The Palestinian armed group earlier said dozens of civilians were killed and injured in Israeli strikes on a residential building in the district.
Katz warned on Sunday that many more of Obeida's criminal partners would be targeted with the intensification of the campaign in Gaza - a reference to a recently approved Israeli plan to seize control of Gaza City.
Separately, the IDF and Shin Bet offered more details about Saturday's strikes that targeted the Hamas spokesman, stating that the operation had been made possible due to prior intelligence gathered by [Shin Bet] and the IDF's Intelligence Directorate that had identified his hiding place.
Five missiles struck the second and third floors of the six-storey apartment building simultaneously from two different directions. The targeted flat had been used as a dentist's surgery. Witnesses reported hundreds of thousands of dollars flying into the air because of the strike, with large sums stolen and later recovered by Hamas members.
Obeida was among the few remaining senior members of Hamas's military wing from before its deadly October 2023 attack on southern Israel.
The joint statement said Obeida served as the public face of the Hamas terrorist organization and disseminated Hamas' propaganda. Over the past few years, Obeida - believed to be about 40 years old - delivered a number of long diatribes against Israel on behalf of Hamas's military wing, the al-Qassam Brigades.
Always masked in a Palestinian scarf, he became an idol to Hamas supporters throughout the Middle East. In what may have been his final speech on Friday, Obeida said the fate of remaining Israeli hostages would be the same as that of Hamas fighters, warning Israel against its planned invasion of Gaza City.
On Saturday, Hamas accused the IDF of hitting a residential building in the densely populated al-Rimal neighbourhood of Gaza City. Local journalists reported that at least seven people had been killed and 20 injured in the strikes, with children among the casualties.
The IDF said that prior to the attack many steps were taken to reduce the chance of harming civilians, including the use of precision weapons, aerial observations, and additional intelligence information.
In early August, Israel's security cabinet approved a plan to seize control of Gaza City in a fresh offensive aimed at bringing the 22-month-long war to an end. The UN has repeatedly warned that a complete military takeover would risk catastrophic consequences for Palestinian civilians and Israeli hostages held in Gaza.
Israeli Prime Minister Benjamin Netanyahu has vowed to defeat Hamas and has defied international criticism of his plans to expand the war. Israel's military operation in Gaza began in response to the Hamas-led October attack, which resulted in the deaths of approximately 1,200 people and the abduction of 251 others.
Since then, more than 63,000 Palestinians have reportedly been killed, according to the Hamas-run Gaza health ministry. While the operation to capture Gaza City has yet to fully commence, Israeli attacks on the city, which is home to nearly a million residents, have been ongoing.
The Israeli military plans to evacuate Gaza City's entire population to shelters in the south before engaging troops. Most of Gaza's population has already faced multiple displacements due to the conflict. More than 90% of homes in the city are estimated to be damaged or destroyed, with critical health, water, and sanitation systems collapsed.
Last week, conditions of famine were confirmed in Gaza City and surrounding areas for the first time.
