Lebanon's militant Hezbollah group is introducing new tactics and weapons against Israel as the war in Gaza drags on and Israeli troops enter parts of the southern city of Rafah. In recent days, Hezbollah has used a drone equipped with missiles to attack an Israeli post as well as an explosive drone to hit its deepest target so far since the clashes began seven months ago. With Israeli troops marching into Rafah and Hezbollah saying the fighting will not stop along the Lebanon border until the war in Gaza ends, tens of thousands of displaced Israelis and Lebanese are not expected to return home soon.
