A Lebanese official confirmed to Al-Jazeera on Wednesday that Lebanese-Israeli discussions in the Washington round of negotiations are progressing well and that there is "U.S. understanding of the Lebanese approach."

The source added that the Lebanese delegation is pushing for a comprehensive solution that addresses both the Israeli withdrawal and the extension of state authority in parallel.

Two paramedics were killed on Wednesday in an Israeli strike on the country's south, with at least 130 emergency and health workers now killed since the Israel-Hezbollah war began in March.

A ministry statement said that "the Israeli enemy directly targeted an ambulance belonging to the Risala Scouts Association", which is affiliated with Hezbollah ally the Amal movement, adding that "this resulted in the martyrdom of two paramedics and left a third with highly critical injuries."

The State Department said progress was made during the first day of talks between Lebanon and Israel in Washington on Tuesday.

"Progress continues on the political and security tracks as we break from the failures of the past 20 years and advance toward a comprehensive agreement aimed at restoring Lebanon’s sovereignty and ensuring Israel's security," the State Department said, adding that "the United States remains fully committed to facilitating these historic negotiations."

Israel warned overnight the Christian neighborhoods in the coastal city of Tyre that Hezbollah members are among them.

Many Lebanese Shiite Muslims fled to those areas in recent days because they were spared from the aerial bombardment along the Mediterranean coast.

An Israeli strike Wednesday hit a car on a busy highway just south of Beirut, hours before the second day of talks between Lebanon and Israel in Washington are set to take place.

The strike in Khaldeh came without warning, and it was not immediately clear if the person targeted was killed.

President Joseph Aoun condemned Wednesday Iranian attacks on "civilian targets" in Kuwait and Bahrain.

The attack on Kuwait's airport wounded at least 63 people and killed an Indian national.

They went to war together against Iran, but Donald Trump and Benjamin Netanyahu's relationship is under strain after the U.S. president reportedly called the Israeli premier "crazy."

Trump unleashed a profane tirade over the phone at Netanyahu over Israel's threats to bomb the Lebanese capital Beirut, fearing it would undermine talks with Tehran, the Axios news outlet and ABC News reported.

The Israeli military said it intercepted two projectiles that crossed into Israeli territory from Lebanon on Wednesday, after earlier announcing the interception of a "hostile aircraft" that had also crossed into Israel.

"Following the sirens that sounded a short while ago in the area of Misgav Am, the Israeli Air Force intercepted two projectiles that crossed from Lebanon into Israeli territory," the military said, referring to a community on the northern border.

The United Nations chief has proposed three options to help end the decades-old conflict between Lebanon's Iran-backed Hezbollah militants and Israel when the 8,100-member U.N. peacekeeping mission in southern Lebanon ends on Dec. 31.

All of the options presented to the U.N. Security Council by Secretary-General Antonio Guterres would continue U.N. military monitoring of the boundary between Israel and Lebanon, support Lebanese forces in deploying throughout the country and strengthen political efforts to end the fighting, which has persisted despite a nominal ceasefire.

Lebanese state media reported an Israeli strike near Beirut on Wednesday as well as attacks on south Lebanon, ahead of a second day of talks in Washington between Israel and Lebanon.

The state-run National News Agency (NNA) reported "the targeting of a car on the Khaldeh road", referring to an area at the southern entrance to the capital.
