Israel’s caretaker Prime Minister Yair Lapid held his first Cabinet meeting Sunday since taking over as leader, promising a functional government despite the political instability that is sending Israel to its fifth elections in less than four years.

Lapid, sitting next to his predecessor power-sharing partner Naftali Bennett, also warned that Israel would take any step necessary to defend itself after it shot down three unmanned aircraft launched by the Lebanese militant group Hezbollah.
