Military officials from Israel and Lebanon held "productive" talks in Washington on Friday, a U.S. official said, adding that the meeting will complement upcoming diplomatic discussions.

Hezbollah said on Saturday it fired rockets at the northern Israeli settlement of Kiryat Shmona, as exchanges of fire between the two sides have intensified despite Lebanon-Israel negotiations.

Israel's military issued evacuation warnings on Saturday for residents of seven villages in southern Lebanon, after Israeli Prime Minister Benjamin Netanyahu said Israeli forces had pushed deeper into the country.

Speaker Nabih Berri said that what concerns him at the present time and what he is intervening in is "preventing any recklessness or internal problems."

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.
