Prime Minister Benjamin Netanyahu ordered members of the Diplomatic-Security Cabinet to adhere to the forum's official positions when publicly commenting on Israel's policy in Gaza.
Speaking at a conference in Jerusalem, Housing and Construction Minister Yoav Gallant told the audience that Hamas military leader Yahya Sinwar "is living on borrowed time. He won't end his life in a retirement home."
At the same event, Public Security Minister Gilad Erdan said that "a shift from a defensive to an offensive policy against Hamas means the targeted assassinations of terrorist leaders who are members of Hamas' military wing."
He added that Israel is "closer than ever to seizing control of the Gaza Strip."
Justice Minister Ayelet Shaked, who also addressed the conference, described U.S. President Donald Trump's regional peace plan, which has yet to be presented, "a waste of time."
The statements prompted Netanyahu to admonish the ministers, saying, "You have to stick to the positions set by the cabinet in terms of what you can and cannot say."
Opposition Leader Tzipi Livni (Zionist Union) criticized the government Tuesday, saying, "If you want to shoot, shoot – don't talk. Empty statements that are not backed by actions are the worst blow you can deal Israel's deterrence."
