An explosion that ripped through a wedding celebration in southern Iran on Tuesday likely resulted from a direct hit by a US munition and not a ricochet off another target, according to an analysis on Thursday by weapons experts who reviewed images and video verified by Reuters.
The US has not accepted responsibility for the incident. President Donald Trump's administration is facing growing domestic public pressure to end a war that is weighing on his approval ratings ahead of crucial November midterm elections.
Iranian state television on Thursday said a 22-year-old woman had died in hospital following the strike that hit a home during a wedding, taking the total reported death toll to five. Iranian officials said nearly 70 were wounded.
Funeral-goers assembled in the late afternoon on Thursday outside the village of Kuhestak in Sirik County, along a stretch of the Strait of Hormuz coast that was hit by heavy US airstrikes late on Tuesday, to mourn their loved ones.
Vance on Thursday told reporters the US was looking into the incident.
"We're investigating it because obviously we care. We want to know," he said.
"If we do make mistakes - again, this is a big difference between us and Iran - when our military makes mistakes they learn from them to try to get better from them."
The US military said it was aware of the Iranian reports but it "never targets civilians".
A US official speaking on condition of anonymity said the government was looking at various scenarios related to the casualties at the wedding, including whether they were caused by a US strike, some sort of ricochet of an Iranian air defence missile, or an errant interceptor itself.
Reuters shared video and images of the incident with four military weapons experts who said the damage was consistent with a direct hit, as opposed to secondary damage from a munition ricocheting off a different target.
Three of the experts said the munition was likely a US weapon, rather than an errant Iranian air defence missile. One of the experts said the weapon may have simply missed its objective.
The attack came some six months after a missile destroyed a primary school in an incident that Iranian officials said killed more than 175 children and teachers.
Reuters previously reported that an initial, internal US military investigation showed US forces were likely responsible for that strike. The Pentagon has not publicly released the findings of its probe.
At the funeral on Thursday for four victims from the wedding, Iran's Mehr news agency video showed a pickup truck carrying a flag-draped coffin beneath a canopy of palm fronds.
In other footage of the funeral, mourners threw petals into the air as doleful music played from a loudspeaker. A casket was carried past a row of soldiers standing at attention with rifles.
Washington launched the airstrikes on Tuesday, hitting what it said were military targets along the coast in retaliation for Iranian attacks on shipping in the Strait of Hormuz.
Iran reported 18 dead in the last US assault.
It responded on Wednesday to the US strikes with attacks on US bases in Iraq, Jordan, Qatar, Kuwait and Bahrain, and carried out further attacks early on Thursday, saying it was targeting another US base, in Kuwait.
Kuwait's military said its air defences had intercepted missiles and drones.
But following that, the war's biggest flare-up since July appeared to subside, with no more major attacks from either side reported on Thursday.
