The US has reportedly launched probe into a wedding strike in Iran that analysis shows was directly hit by American munition.
This as an Iranian health official reports three days of US bombings have left at least 18 people dead and 142 others injured from August 30 to September 2.
In Vienna, Jordan's foreign minister rejects any attempts to transform the kingdom into a battlefield.
The southern port town of Kuhestak is one of a string of cities along the Strait of Hormuz coastline that recently came under American fire.
Destruction caused by a missile strike is still visible at a house where dozens of people celebrated the wedding of a fisherman's daughter on Tuesday.
Security footage showed fireballs lighting up the night sky.
Iranian media reported two women and two children were killed in the area and more than 60 injured. An injured person later died, bringing the tally to five on Thursday.
The pictures of some wedding victims are being displayed at the entrance of the town.
US Vice President J.D. Vance says he's looking into reports of the attack but claims his country has never targeted civilians in combat.
At a White House briefing, Vance notes roughly 15 million barrels of oil passed through the Strait of Hormuz on Wednesday, declaring that oil shipments have "almost" returned to pre-war levels.
However, chairman of the National Security and Foreign Policy Committee of Iran's Parliament Ibrahim Aziz says the waterway will not open without Tehran's consent.
Jordan's Foreign Minister Ayman Safadi on Thursday says his country is not part of the war, but Iranians launched attacks targeting Jordan and the broader Arab region shortly after the outbreak of the conflict.
Safadi has rejected claims that Jordan hosts independent American bases.
He does acknowledge "There are American troops embedded in Jordanian bases as part of a longstanding cooperation."
The arrangement, which also includes German, French and Austrian troops, is part of Jordan's effort to develop its defence capabilities through international cooperation, the top diplomat explains, as he urges immediate de-escalation to ensure regional stability.
