The US president says he confronted the Israeli prime minister over Israel's attack on Lebanon

US President Donald Trump has confirmed reports that he called Israeli Prime Minister Benjamin Netanyahu "f***ing crazy" during a heated phone conversation over Israel's military operations in Lebanon.

Axios reported earlier this week that Trump had angrily urged Netanyahu to cancel planned strikes on Beirut, warning that further escalation could jeopardize ongoing US-Iran negotiations and a fragile regional ceasefire.

Speaking on the New York Post's 'Pod Force One' podcast on Wednesday, Trump acknowledged using the language attributed to him.

"I did," he said when asked whether he had called Netanyahu "f***ing crazy." 

"I was a little bit perturbed at his constantly fighting with Lebanon. At some point I said, 'We gotta stop this. We gotta stop it.'" Trump added that he still had a "very good relationship" with the Israeli leader.

The US president also dismissed claims that Netanyahu had pushed him into the conflict with Iran, saying anyone making such accusations was "the enemy."

Israel has intensified its campaign in Lebanon in recent days, carrying out strikes it says are aimed at Hezbollah commanders and infrastructure. Israeli troops have also advanced further into southern Lebanon, including the capture of Beaufort Castle, a medieval fortress overlooking the Litani River.

Lebanese health authorities said on Wednesday that more than 3,500 people have been killed in Israeli attacks since early March. The escalation has drawn criticism from Tehran, which insists that the US-Iran ceasefire framework also covers Lebanon.

Iranian parliament speaker Mohammad Bagher Ghalibaf warned on Tuesday that continued Israeli operations could derail diplomacy.

"If the Israeli aggression against Lebanon continues, we will not only halt the path of negotiations, but we will also be in direct confrontation with the enemy," he wrote on X.

The tensions come as the eight-week-old ceasefire between Iran and the US faces renewed strain. US Central Command said it carried out "self-defense strikes" on Iran's Qeshm Island on Wednesday, while the IRGC said it targeted US-linked assets in the Gulf in retaliation for recent American attacks. Kuwait International Airport was reportedly struck during the exchange.
