Delegates walked out before the Israeli leader spoke at the United Nations General Assembly, removing part of the audience before his address.

Facing that emptying of the chamber, he used his time at the podium to defend Israel's military action. During his remarks he directed a sharp rebuke at those who left, calling them "moral cowards".

The walkout occurred prior to the start of his speech, and his defence of the military measures was delivered in front of the delegates who remained. The rebuke, expressed in those two words, was positioned as a direct response to the departures.

The moment combined a public interruption of the assembly's usual proceedings with an insistence from the Israeli leader that his country's conduct required justification. His comments tied the decision by some delegates to exit the chamber to a broader moral judgement he applied from the podium.

The sequence — an early walkout followed by a forceful defence — framed the UN appearance around both a visible withdrawal of delegates and an uncompromising defence from Israel's representative. The president of the General Assembly and the assembly's seating of member delegations were the institutional context for the exchange.

What unfolds next, including any formal responses from member states or further actions in the General Assembly, was not set out in the reported account of the speech. The immediate facts remain the walkout, the defence of military action, and the label applied to those who departed.
