Hezbollah has warned of a "dangerous escalation" in the region, saying Washington bears "full responsibility" for the "treacherous" raids on Iran launched by its Israeli ally.

"Hezbollah strongly condemns the treacherous Zionist aggression against the Islamic Republic of Iran and considers it a dangerous escalation at the level of the entire region," Hezbollah said in a statement.

Lebanon's state news agency on Sunday reported a series of overnight Israeli airstrikes on Beirut's southern suburbs, after Israel's army issued fresh evacuation calls.

The official National News Agency said shortly after midnight that Israel had "targeted the southern suburbs of Beirut."

Iran warned it would defend itself after Israeli air strikes killed at least four soldiers and further stoked fears of a full-scale war in the Middle East.

A Lebanese political leader has expected Israel's war on Lebanon to end soon, telling al-Joumhouria newspaper that there are two factors that support his suggestion.

The Israeli army said that a strike that killed three journalists in south Lebanon was "under review," maintaining that it had targeted Hezbollah militants.

A series of Israeli strikes hit Beirut's southern suburbs late Friday, Lebanese state media reported, as AFPTV footage showed smoke rising from the area after Israel's army issued an evacuation call.

Lebanon's official National News Agency said "enemy aircraft" carried out at least eight strikes on the area, a Hezbollah stronghold, targeting districts including Haret Hreik, Burj al-Barajneh and Laylaki.

Hezbollah on Saturday said it had launched drones against an Israeli air base south of Tel Aviv, its first claimed attack against the facility.

At war with Israel since last month, after a year of tit-for-tat cross border exchanges, Hezbollah regularly announces the targeting of Israeli military facilities but its statement that it launched "an aerial attack with drones" against Tel Nof base was the first claim of its kind in one year.

Hezbollah said it fired a barrage of rockets on Saturday at Israeli forces near a village in southern Lebanon, where the Israeli army has carried out ground incursions for weeks.

The Israeli military said it intercepted two drones crossing into Israel from Lebanon on Saturday, hours after Israel struck several military targets inside Iran.

Lebanese state media said the Israeli army dynamited houses in a Lebanese border village on Saturday, more than a month into its war with Hezbollah.
