There's concern for wider conflict in the Middle East as Israel and Hezbollah 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 around 500 people have been killed in air strikes.  

Journalist and analyst Gideon Levy told Mike Hosking there's no incentive, mediator or leadership in stopping it. 

He said that Israel insists on its own conditions, Hezbollah seems to be ready to sacrifice, and we are stuck in another bloodbath.
