Iravani addressed a letter to the UN, denouncing Israel's explicit admission of responsibility for the assassination of Ismail Haniyeh.

Israel confirmed Monday that it assassinated Hamas leader Ismail Haniyeh and issued a stark warning to the leadership of Yemen’s Houthi group, threatening similar action.

The comments by Israel Katz appeared to mark the first time that Israel has acknowledged killing Ismail Haniyeh, who died in an explosion in Iran in July. Israel was widely believed to be behind the blast and leaders have previously hinted at its involvement.
