Hezbollah will confront "Israeli-American aggression" and will not surrender despite the "imbalance in capabilities", the head of the Iran-backed Lebanese group Sheikh Naim Qassem said Wednesday night in a televised speech.

The Israeli military told residents living south of Lebanon's Litani river to immediately head north on Wednesday, warning that the Israeli army was "compelled to take military action" against Hezbollah in the area.

Hezbollah said on Wednesday it had targeted the headquarters of Israel Aerospace Industries, in central Israel, overnight with a drone attack while also saying it launched a missile at a drone control base.

Israeli strikes hit a Beirut hotel and residential complex in Lebanon's east, Lebanese state media said Wednesday, as Israel announced broad strikes in response to Hezbollah missile and drone launches.

Hezbollah said it targeted northern Israel's Haifa naval base on Tuesday, its 12th attack of the day as Israel continued to strike Lebanon, including Beirut's southern suburbs

In a statement, the group said that "in response to the criminal Israeli aggression that struck dozens of Lebanese cities and towns, including Beirut's southern suburbs", it targeted the base with "a barrage of high-quality missiles" at 8:00 pm local time.
