Iran has launched attacks on Kuwuit’s international airport, killing one person and injuring 63 others, as hostilities flared up again in the Gulf and tested a shaky ceasefire.

Kuwait’s government released video showing the aftermath of the Iranian drone and missile strikes in the airport’s passenger building in terminal 1, which was badly damaged.

Flights were suspended after the attack. Kuwait Airways and Jazeera Airways ‌had since resumed flying after taking safety measures, the civil aviation authority said.

Earlier, Iranian media reported that Iran’s elite Revolutionary Guards had attacked the headquarters of the US Fifth Fleet in Bahrain and a US airbase, as well as a vessel identified as Panaya.

US Central Command denied its bases had been hit. CENTCOM said it had carried out a round of “defensive strikes” in southern Iran, among other attacks on missile launch sites and Iranian boats.

US President Donald Trump said again on Thursday (AEST) that a deal was imminent with Iran.

“They’re pretty close to signing a paper,” he said.

In an earlier podcast interview, Trump said Iran had “already agreed they’re not going to have a nuclear ​weapon”.

Trump confirms ‘crazy’ call

In his podcast comments, Trump also acknowledged having called Israeli PM Benjamin Netanyahu “crazy” in a reportedly expletive-filled phone ​exchange over the fighting in Lebanon as he sought a deal over the wider war.

Trump was asked whether he had called ‌the Israeli leader “effing crazy” and accused him of ingratitude, paraphrasing a report by Axios.

“I did,” Trump told the Pod Force One podcast.

“I wouldn’t say angry. I was a little bit perturbed at his constantly fighting with Lebanon, you know.”

Trump went on to say he and Netanyahu ‌got along ‌well.

According to ⁠the Axios report, which cited an unidentified US official, Trump said ​to Netanyahu in a call on Monday: “You’re f–king crazy. You’d be in prison if it weren’t for me. I’m saving your ass. Everybody hates you now. Everybody hates Israel because of this.”

Trump said in the interview: “At some point I said, Bibi, we got to stop this. We got ⁠to stop it.”

Iran has said it will not ‌agree ​to a deal with the US to end the war that Trump and Netanyahu ​launched in late February, ‌unless a ceasefire also covers Lebanon, which Israel invaded in March in pursuit of ​the Iran-aligned Hezbollah militia that fired across the border in support of Tehran.

Hostilities have continued despite a US-mediated agreement announced on Monday that led Israel to step back ​from attacking ​the Hezbollah-controlled southern suburbs of Beirut, and ​the Iran-backed group to halt cross-border strikes.

Israeli ‌drone strikes killed at least six people in southern Lebanon and targeted a car just south of Beirut on Wednesday, Lebanese security sources said. Israel said it intercepted a hostile aircraft likely fired by Hezbollah.

Trump bristled when asked if Netanyahu “tricked” him into attacking Iran, saying his critics ​were “the enemy”.

Trump has used expletives about Israel in the past, including publicly saying last ​year that Israel and ⁠Iran “don’t know what the f— they are doing”.
