Operations in Lebanon
Yesterday, the IDF announced the names of 8 soldiers who fell in Lebanon - where Israel began limited ground operations this week as it seeks to ensure the safe return of residents to northern Israel.
Hezbollah has been firing rockets at civilian populations since October 8, a day after Hamas's attacks on southern Israel which saw the murder of over 1200 people.
