(JTA) — The leader of Lebanon’s militant Hezbollah group said “millions” of Israelis will be displaced if there is a new conflict between the Shiite group and the Jewish state.

Sheik Hassan Nasrallah made the remarks Friday during a rally in southern Beirut, responding to a comment from Israel that a future war could displace more than a million Lebanese, The Associated Press reported.

On Thursday, the Jerusalem Post quoted an unnamed Israeli military official saying that if given no choice, Israel would “evacuate 1 million, 1.5 million residents in Lebanon, and act.”
