The U.S. and Iran are yet to agree a deal over the Strait of Hormuz.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.
Delegations from the U.S. and Iran entered negotiations in June aimed at a war-ending deal based on a memorandum of understanding signed by both countries.
The U.S. and Iran have nonetheless continued to exchange strikes, with the strategic Strait of Hormuz the primary flashpoint.
The United Kingdom Maritime Trade Organization (UKMTO) Centre said in an alert on Tuesday that it received a report of a vessel being struck by an "unknown projectile" while transiting the Strait of Hormuz.
"The impact caused damage to the engine room and resulted in a crew casualty. The remaining crew are currently being assisted by the Omani Coast Guard," the alert read.
Stephane Dujarric, the spokesperson for United Nations Secretary-General Antonio Guterres, on Monday reported an "alarming and concerning intensification of violence" in southern Lebanon over the weekend.
The United Nations Interim Force in Lebanon -- UNIFIL -- recorded what Dujarric said were "intense kinetic activities across its area of operations over the weekend," including several Israel Defense Forces airstrikes, helicopter attacks, indirect fire and maritime actions in Lebanese waters.
"Meanwhile, UNIFIL peacekeepers discovered and neutralised several unexploded ordnance. Peacekeepers also continued to encounter restrictions on their freedom of movement and incidents of aggressive behavior," Dujarric said.

While President Donald Trump said on Monday that the U.S. has "total control" over the Strait of Hormuz, Energy Secretary Chris Wright told Fox News that the Strait is still a "conflict zone" where disruptions to ship traffic remain, acting as hurdles to transporting oil and gas.
Wright said that trackers of the ships going through the Strait have been turned off due to the conflict, meaning public data does not accurately reflect the true number of vessels transiting the Strait. He asserted that 30 ships went through the waterway on Sunday and that "millions" of barrels have been moving through per day.
Wright said that U.S. military escorts of commercial shipping demonstrate the control the U.S. has over traffic in the strait, but did not acknowledge the Iranian threat that necessitates those escorts and that continues to keep traffic low.
Wright was pressed over the fact that these numbers of ships moving through the Strait are still lower than pre-war levels. He said he couldn't predict the future when asked when he thinks those traffic levels would rise.
"We're fixing a 47-year-old problem with this government in Iran and the threat of nuclear weapons, but it does cause some disruption in the short term. President Trump's policies have made us ready for that disruption," Wright said.
When asked about a timeline for the end of the war, Wright said Trump is "playing the long game."

Masrour Barzani, the prime minister of the semi-autonomous Kurdistan Regional Government in northwestern Iraq, said in a post to X on Monday that his personal office was targeted by Iranian drone attacks.
Drones also targeted the home of the head of the region's security and intelligence agency, Barzani said in his post.
"I condemn these reckless and unacceptable attacks in the strongest terms. This is a dangerous escalation and a direct threat to the security and stability of the Kurdistan Region," he wrote. "These attacks will not deter us from carrying out our duties and protecting our citizens."
Iraqi Prime Minister Ali al-Zaidi said in a statement that he had ordered a probe into "the sources and origins of the attack."
