The evacuation warnings come ahead of planned strikes, despite a ceasefire intended to halt the war with Lebanese militant group Hezbollah.
The military’s Arabic-language spokesman, Colonel Avichay Adraee, issued two successive warnings – first for 13 villages, then for 16 more, with the second targeting communities north of the Zahrani river.
Earlier, Israeli military said two drones, suspected to have been launched by militant group Hezbollah from Lebanon, struck northern Israel on Sunday but caused no casualties.
“Two impacts of suspicious aerial targets in Israeli territory were identified near the Israel-Lebanon border. No injuries were reported,” the military said.
In the wake of the strikes, two far-right Israeli ministers called for retaliatory strikes on Beirut’s southern suburbs, a Hezbollah stronghold known as Dahiyeh.
