Hezbollah has again rejected direct talks between Lebanon and Israel on the eve of military negotiations between the two sides.

Lebanon's culture minister told AFP on Friday that Israeli strikes on the country's south are putting heritage sites, including in the ancient city of Tyre, in "serious danger".

Lebanese authorities have decried Israeli attacks near UNESCO-protected historic sites and landmarks in the country's south.

Lebanon's health ministry said an Israeli strike south of Beirut on Thursday killed a woman and two children, after Israel's army said it "precisely struck" the capital without identifying the target.

Israel's air force carried out an airstrike on the Choueifat area on the edge of Beirut's southern suburbs on Thursday afternoon, the Israeli military said, further straining a fragile ceasefire a day ahead of crucial negotiations in Washington.

The strike hit an apartment building. Videos from Choueifat, close to Beirut's international airport, showed white smoke billowing from a residential neighborhood.

Five people were killed and 21 others wounded overnight when an Israeli drone struck an apartment building in the southern city of Sidon where some displaced families lived, the first such attack on Sidon during the latest escalation.

The attack likely came in response to a drone attack that killed a female Israeli soldier in north Israel. LBCI television had reported that Israel had informed the U.S. of its intention for escalation after the attack.

The Israeli military said on Wednesday that all areas south of Lebanon's Zahrani River, which runs roughly 40 kilometers (25 miles) north of the Israel-Lebanon border, were considered "combat zones" and urged residents to head north.

The Israeli military said on Thursday it had begun new strikes on Hezbollah infrastructure around the southern Lebanese city of Tyre after issuing an evacuation warning to its residents.

The Israeli military said on Thursday that a soldier was killed the day before by a Hezbollah drone near the Lebanon border, taking to 24 the number of its troops killed in the war with the Iran-backed group.

The reason the Israeli army has not carried out an attack in Beirut and its southern suburbs despite the latest escalation is an "American veto," unnamed sources told Israeli newspaper Yedioth Ahronoth on Wednesday.
