The spokesperson for the Israeli army, Avichay Adraee, wrote on X:

“Hezbollah’s activities force the Israel Defense Forces to act against them with force. The IDF does not intend to harm you.
For your safety, you must evacuate your homes immediately. Anyone near Hezbollah members, facilities, or military equipment is putting their life at risk.
Any home used by Hezbollah for military purposes may be targeted. To residents of southern Lebanon, you must move immediately north of the Litani River. To ensure your safety, evacuate your homes at once and relocate north of the Litani River.
Be aware that any movement south may put your life in danger.”
