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 military adviser to Iran's supreme leader on Wednesday warned of more missile and drone strikes should the United States renew its attacks on Iran.

"Every shot fired and every attack will be met with a deluge of missiles and drones," Mohsen Rezaei posted on X, adding that "the aggressor will swiftly be punished".

A top Emirati official called on Wednesday for a united stance from the Gulf after renewed attacks on Kuwait and Bahrain that were blamed on Iran.

"In light of Iran's repeated aggression against the brotherly states of Kuwait and Bahrain, a firm, unified and cohesive Gulf stance is imperative. No Gulf state should be left to face these attacks alone, because the security of the Gulf Cooperation Council (GCC) states is interconnected, their interests are shared, and their destiny is one and the same," said UAE presidential advisor Anwar Gargash in a post on X.

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.

Kuwait on Wednesday said Iranian attacks on its territory killed one person and wounded several others, as well as forcing its airport to close and damaging unnamed diplomatic missions.

Kuwait's foreign ministry condemned the attacks "that once again targeted vital and civilian infrastructure, including Kuwait International Airport, killing one person and injuring others, in addition to causing damage to vital infrastructure including diplomatic missions".

Israeli Prime Minister Benjamin Netanyahu announced on Tuesday allocations of 13 billion shekels (more than $4.5 billion) to secure and develop northern communities along the Lebanon border, battered by weeks of fire from Iran-backed Hezbollah.

"The government made dramatic decisions today to strengthen the north. We are investing more than 13 billion shekels today, in addition to the seven billion we have already provided -- a total of 20 billion shekels going to the communities of the north," Netanyahu said following the government's approval of the measure.

Israeli strikes on southern Lebanon on Tuesday killed five people, including a child, and wounded 48, the Lebanese health ministry said.

Those wounded in the strikes across the south included "a doctor and five employees of Tebnine Governmental Hospital, which sustained damage in yet another episode of the series of attacks carried out by the Israeli enemy against hospitals and health centers", the ministry said in a statement.

Secretary of State Marco Rubio on Tuesday expressed hope that a deal to end the war in Iran was in the cards, stressing that Tehran must severely curtail its nuclear program before any sanctions are lifted.

U.S. President Donald Trump said Tuesday that the United States and Iran were speaking "continuously," denying reports that Tehran had broken off contact over Israel's attacks on Lebanon.
