ERBIL, Kurdistan Region of Iraq - US Vice President JD Vance on Thursday said that he is "skeptical" regarding Iranian claims that a US airstrike hit a wedding party in Sirik this week and killed five civilians, adding, "Obviously, sometimes things happen."

During overnight US strikes on Iran into the early hours of Wednesday morning, Iran said that a strike on a wedding party in Sirik's Kohstak wounded over 70 people, noting that most of the casualties were women and children.

Video footage shared by Islamic Revolutionary Guard Corps (IRGC)-affiliated media showed scenes of chaos at the wedding event, with debris and rubble scattered around celebrants.

Iranian state TV subsequently confirmed that at least five people were killed in the bombardment, including a four-year-old child, with the fifth fatality being a 22-year-old invididual who succumbed to grievous wounds on Thursday.

When asked about the matter during a White House press conference, Vance said "I know that we're investigating," caveating that "Iranian state media has not been a very good scribe about what's happened in the conflict thus far," rendering him "extremely skeptical" of the claims.

"Obviously, sometimes things happen," he added, referring to civilian casualties in the war. "When our military makes mistakes, they learn from them to try to get better from them, so we're investigating it very fully."

The Iranian foreign ministry on Wednesday slammed the attacks, calling them "brutal war crimes" that are reminiscent of the Minab bombing during the opening days of the US-Israeli war on Iran in which Washington struck an elementary school in southern Iran, resulting in the deaths of over 150 people, most of whom were schoolchildren.

The administration of US President Donald Trump has yet to claim responsiblity for the atrocity despite an investigation having been ordered.

Speaking regarding the war writ large, Vance said that Iran's control of the Strait of Hormuz is "effectively gone" and that oil transit through the waterway is "almost back to where it was before the conflict even started."

"When will the Iranians stop shooting at ships?" Vance asked rhetorically, adding that the impact of Iranian strikes on vessels breaching its blockade has "less effect" on world energy markets "day by day."
