Israel and militant group Hezbollah are continuing to trade strikes.  

Israel's Defence Force says its mission is to stop the Iranian-backed Hezbollah firing rockets into Israel's north, and to push it back from the border.  

Lebanon's health ministry says more than 500 people have been killed in air strikes.  

US correspondent Richard Arnold told Mike Hosking that President Biden has called for a ceasefire in the Middle East, speaking at the UN General Assembly.  

He says his comments focused on Israeli and American hostages who remain alive after the Hamas raid last October.
