The apology was made during a telephone conversation between Putin and Israeli Prime Minister Naftali Bennett, according to the prime minister’s staff.
The Kremlin’s version of the conversation, which took place on Thursday, does not mention any apology.
It was in an interview with Italian television recently that Lavrov drew parallels between Ukrainian President Volodymyr Zelensky and Adolf Hitler.
The statement was sharply criticized, including Israeli Foreign Minister Yair Lapid saying it was unforgivable and terrible.
Israel has so far been hesitant about the war in Ukraine. The country has not participated in the Western countries’ major sanctions package or sent any weapons to Ukraine.
During the talks, Putin claimed, among other things, that civilians could still leave the Azovstal steelworks, according to a statement from the Kremlin. He also called on Kyiv to order the fighters in the steelworks to lay down their arms.
