Iranian Foreign Minister Abbas Araghchi said Wednesday that lines of communication with the United States were still open, but "no tangible progress" has been made in negotiations to end the Middle East war.

"Communications with the Americans have not been cut off, and messages have been exchanged regarding the need to stop aggression against Beirut, but no tangible progress has been made in the negotiation process," the Tasnim news agency quoted him as telling Lebanon's Al Mayadeen TV.

The fate of Iran's highly enriched uranium stockpiles is at the center of talks with Washington, and Tehran has not yet agreed to a peace deal, U.S. Secretary of State Marco Rubio said Wednesday.

Washington insists that Iran must turn over its near-weapons-grade enriched uranium, agree to curb its nuclear activities and re-open the Strait of Hormuz for any peace agreement to take hold.

Israeli Prime Minister Benjamin Netanyahu said on Wednesday that Iran was "playing with fire" after the Islamic republic carried out an attack on Kuwait.

"Iran surely knows what the (U.S.) president has said, that if necessary, there'll be a full-scale return to military action," Netanyahu said in an interview with U.S. channel CNBC when asked if there was still a ceasefire following recent attacks on Kuwait and Bahrain.

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.

"Any attack on Beirut will have grave consequences and will lead to a full-scale resumption of the war," the Tasnim news agency quoted Araghchi as telling Lebanon's Al Mayadeen TV. "Our armed forces are ready to strike Israel if it attacks Beirut."

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.

Trump confirmed in an interview published on Wednesday in the New York Post that he had a tense exchange with Netanyahu two days prior, in which he reportedly berated his close ally with expletives.

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."

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.

U.S. President Donald Trump said he "would like to meet" Iran's supreme leader Mojtaba Khamenei, in an interview published Wednesday.

"I would like to meet him, and we probably will meet at some point, depending on how it all works out," Trump told the New York Post's "Pod Force One".

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.
