Iranian Foreign Minister Abbas Araghchi warned on Wednesday that any attack on Lebanese capital Beirut would trigger a "full-scale resumption" of the Middle East war, as Israel pressed its campaign against Lebanese militant group Hezbollah.

The estimations suggest that Israel will attack Beirut in the coming days, Israeli officials told Israel's Channel 13 on Wednesday, after Hezbollah claimed a rocket attack on north Israel.

Israeli Prime Minister Benjamin Netanyahu downplayed on Wednesday a row with U.S. President Donald Trump, saying they both were aligned on the goal of disarming Hezbollah in order to achieve peace between Israel and Lebanon.

U.S. Secretary of State said Wednesday that he hopes the latest round of high-level political talks between Israel and Lebanon will result in a joint statement on ending hostilities.

In testimony before lawmakers that started Wednesday shortly after the Israeli and Lebanese ambassadors to the U.S. began meeting at the State Department for a second day of negotiations, Rubio said the aim of the talks is to "produce a joint statement and an action plan on a track for security in that country, independent from Hezbollah, independent from nefarious influence."

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

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.
