Israeli optimism about the success of the assassination of leaders from "Hamas" in Doha has declined.

On Wednesday, optimism among Israeli political and military circles significantly declined regarding the success of the assassination operation targeting leaders of the "Hamas" movement in the Qatari capital, Doha, on Tuesday.

The military correspondent for Israeli Army Radio, Doron Kadush, stated: "Since late last night until this morning, I have heard from multiple sources within the defense establishment many doubts about the results of the Israeli attack that was launched yesterday in Qatar."

He mentioned that two sources in the defense establishment informed him last night and this morning that "things do not look good, and there is no cause for optimism," after they had expressed greater optimism earlier yesterday evening, according to the correspondent.

Kadush continued: "The matter (the killing of Hamas leaders) is still uncertain, and we must, of course, exercise caution, but this is the situation in Israel as of this morning: some pessimism regarding the results of the attack."

For its part, the Hebrew newspaper "Yedioth Ahronoth" stated on Wednesday: "So far, there has been no official Israeli confirmation of the success of the operation."

It added: "The operation shocked the world, but its results are still unclear."

Israeli political and military officials insisted on Tuesday that the assassination operation was successful, despite Hamas confirming its failure to kill the movement's leaders in Doha.

On Tuesday, Qatar announced that Israel launched a "cowardly attack targeting residential premises of several members of Hamas's political bureau in Doha."

The Israeli army quickly announced in a statement that it attacked "the leadership of Hamas" in Doha using the air force in cooperation with the General Security Service "Shabak."

Meanwhile, Hamas announced the survival of its negotiating delegation, led by its chief in Gaza, Khalil al-Hayya, from the assassination attempt, and the killing of his office director, Jihad Labed, and his son, Hamam al-Hayya, along with three companions: Abdullah Abdul Wahid, Moamen Hassouna, and Ahmad al-Mamlouk, and Qatari security personnel Badr al-Humaidi.

Israel, with American support, is committing genocide in Gaza, resulting in 64,605 deaths and 163,319 injuries among Palestinians, most of whom are children and women, along with hundreds of thousands of displaced persons, and famine that has claimed the lives of 404 Palestinians, including 141 children.
