Israel found a drone last week on their northern border that Hezbollah now admits is theirs. Hezbollah is either an Iranian proxy in Lebanon or just Iranian terrorists in Lebanon, depending on your point of view.
Iran is building a bomb, announces they are building UAVs that can carry bombs, and just admitted they or their proxy could get a UAV into northern Israel.
Bomb, means to deliver it and ability to get it to target.
