Iran launched a deadly new set of attacks in the Persian Gulf on Wednesday as it traded strikes with the United States, the latest exchange to threaten the fragile ceasefire and stalled peace talks between the two countries.

One person was killed and flights were suspended in Kuwait, officials said, after missile and drone strikes, including an attack on its international airport. The U.S. military said it shot down Iranian drones near the Strait of Hormuz and struck Iran’s Qeshm Island a day earlier.

Repeated military exchanges between Washington and Tehran, as well as Israel’s escalating campaign in Lebanon, have added strain to efforts to end the war and reopen the crucial trade route. The two sides offered mixed messages on the status of talks, with President Donald Trump insisting they were ongoing after Iran signaled it may walk away.

In a taped interview that aired Wednesday, Trump acknowledged calling Israeli Prime Minister Benjamin Netanyahu “crazy” during a terse call about Lebanon earlier this week. Trump also said it was “unlikely” the U.S. blockade of Iran would still be in place by Labor Day, adding that he believed the situation would “resolve itself fairly quickly.”

He warned that he would ultimately have to make a “determination: Do we sign a deal or we do it the other way? And the other way is not nice.”

Iranian Foreign Minister Abbas Araghchi said Wednesday that there had been no progress in talks.

“Our communication with the Americans has not been cut off but no progress has been achieved in the negotiations,” he said, according to Iranian state TV.

Araghchi added, “Returning to negotiations will be conditional upon securing the rights of the Iranian people and bringing an end to the war against Iran, Lebanon and the region.”

Araghchi also warned that Israeli attacks in Beirut could jeopardize the ceasefire between Iran and the U.S.

“The result of aggression against Beirut will be the return of war,” Araghchi said, according to the semiofficial Fars news agency.

The latest flare-up in the conflict saw Kuwait report early Wednesday that one person had been killed in an Iranian drone attack. A further 63 people were injured, according to the Kuwaiti Health Ministry.

The attack caused significant damage to Terminal 1 at Kuwait International Airport, said Col. Saud Abdulaziz Al-Atwan, a Defense Ministry spokesman, with all air traffic briefly suspended as a result.

Videos published online and geolocated by NBC News showed a blazing fire inside the airport, surrounded by debris and heavy smoke as people ran for cover. Another showed the roof destroyed, with rubble scattered on the ground as emergency responders surveyed the aftermath.

Kuwait’s military said it had intercepted 13 Iranian missiles and 17 drones since dawn Wednesday. The country expelled two Iranian diplomats following the strikes, condemning the “flagrant violation” of its territorial integrity and the targeting of civilian infrastructure. Kuwait’s Foreign Ministry warned Iran it had a “full and inherent right to defend itself and to take all necessary measures to preserve its sovereignty.”

U.S. Central Command said late Tuesday that Iran had launched several ballistic missiles toward regional neighbors, though it said all of the attacks had “failed to hit their intended targets.”

Two missiles fired at Kuwait had fallen short or broken apart en route, while three missiles launched at Bahrain were immediately intercepted by U.S. and Bahrain air defense forces, it said in a post on X. CENTCOM said its forces also shot down “three one-way attack drones launched by Iran toward civilian mariners that were rightfully transiting regional waters.”

It said American forces had also conducted what it described as “self-defense strikes” on an Iranian military ground control station on Qeshm Island.

Egypt, the United Arab Emirates, Saudi Arabia, Qatar, Oman, Bahrain, Jordan and Lebanon all condemned Iran’s attacks across the Gulf.

CENTCOM announced earlier that it had also disabled a Botswana-flagged tanker as it headed toward Kharg Island, Iran’s main oil terminal, saying in a post on X that the ship’s crew “ignored repeated warnings, failing to comply with directions from U.S. forces multiple times over a 24-hour period.”

It said a U.S. aircraft ultimately disabled the vessel by firing a Hellfire missile into the ship’s engine room, blocking the tanker from reaching Iran, with the post noting that the U.S. military has “disabled six commercial vessels and redirected 122” since a blockade against Iran’s ports was launched April 13.

The Iranian Foreign Ministry on Wednesday said it “strongly condemns the aggressive act of the US terrorist army in attacking an Iranian tanker in the Strait of Hormuz and attacking a telecommunications mast on Qeshm Island.” It said the attacks represented a violation of the shaky ceasefire agreement between the two countries as they look to negotiate a broader deal.

With talks in flux, Iran’s stranglehold on the Strait of Hormuz — a vital trade route through which some 20% of the world’s oil passes — has throttled global energy supplies since the U.S. and Israel launched the war in late February.

Oil prices rose overnight, with the international benchmark Brent crude up by 2% to $98 a barrel.

Meanwhile, the Israeli military launched new strikes in Lebanon on Wednesday as it traded occasional attacks with Iran-backed Hezbollah despite Trump announcing both sides had agreed to de-escalate.

Israel and Lebanon agreed to implement a ceasefire after negotiations in the U.S. on Wednesday, the State Department said in a joint statement released on the behalf of the U.S., Lebanon and Israel.

“As a result of the U.S. led negotiations, Israel and Lebanon agreed to the implementation of a ceasefire. The ceasefire is contingent on a complete cessation of Hizbollah fire and the evacuation of all Hizbollah operatives from the South Litani Sector,” the statement read, using a different spelling for the name of the Iran-backed militant group.

“Pilot zones” will be established where the Lebanese Armed Forces will have “exclusive control of the territory to the exclusion of all non-state actors,” according to the statement.

The statement did not indicate whether Hezbollah had agreed to the terms.

Trump’s intervention came after Tehran threatened to pull out of peace talks over Israel’s attacks in Lebanon.

Trump held a tense call with Israeli Prime Minister Benjamin Netanyahu on Monday, a U.S. official familiar with the call and another source familiar with the call told NBC News.

Trump gave insight into the call during his interview with the New York Post’s “Pod Force One” podcast that aired Wednesday.

Asked if he had called Netanyahu “crazy,” as first reported by Axios, Trump said, “I did.”

“I wouldn’t say angry,” Trump said of his approach, adding that he was “a little perturbed at his [Netanyahu’s] constantly fighting with Lebanon.” Still, he said, “I like Bibi a lot, and I’ve worked very well with him,” using Netanyahu’s nickname.

In an interview with CNBC on Wednesday, Netanyahu said that he and Trump have had “tactical disagreements,” adding: “We always find a way to work them out. And we do so as great friends.”

He warned Iran that it is “playing with fire” by striking the Gulf and said that Israel is “ready” to resume a full-scale return to military action if Trump decides to.

The tensions between the close allies come as Netanyahu faces domestic pressure to keep striking Hezbollah as he prepares for new elections this fall.
