Israeli forces have spent much of the past year destroying Hamas’ vast underground network in Gaza. They are now focused on dismantling tunnels and other hideouts belonging to Hezbollah militants in southern Lebanon.

Israel stepped up air strikes on Lebanon and said a senior Hezbollah commander in the south of the country had been killed, the latest escalation of its conflict with the Iran-backed militant group.

Israel’s military said Thursday it killed a Hezbollah commander in southern Lebanon, while also announcing a new round of evacuation orders in the Bekaa Valley. The Israel Defense Forces identified the commander killed as Hussein Awada and said he was responsible for firing projectiles across the border into Israel.
