Israel launched fresh strikes Monday on Tyre, Lebanese state media said, following an earlier raid that killed seven people.

The National News Agency (NNA) reported "a series of strikes" on the ancient coastal city, beginning with a raid on a residential apartment.

Hezbollah said it fired rockets at a military base in northern Israel on Sunday, a day after it declared several areas in the region a "legitimate target" due to the presence of Israeli troops.

Lebanon's health ministry said at least eight people were killed and 25 others wounded Sunday in an Israeli strike near the southern city of Sidon, where an AFP correspondent said a building was targeted.

The Israeli military on Sunday said four soldiers were killed in southern Lebanon, bringing to 36 the total number of Israeli soldiers killed since the start of ground operations on September 30.

The soldiers "fell during combat in southern Lebanon," the army said in a statement, adding that they were killed on Saturday.

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.
