A group of Democratic lawmakers has formally demanded that the Pentagon clarify whether American forces were responsible for a deadly strike on a wedding gathering in Kuhestak, southern Iran, that reportedly killed five civilians, including two children, on 1 September. The demand, made public on Tuesday, 13 October 2026, marks one of the sharpest congressional challenges yet to the military's conduct during its ongoing campaign against Iran.

The Lawmakers and Their Demands

Representatives Jason Crow of Colorado, Yassamin Ansari of Arizona, and Sara Jacobs of California addressed a letter to Defence Secretary Pete Hegseth, pressing for detailed explanations of the military's targeting decisions, the status of any investigation, and the protective measures in place for civilians. The lawmakers set a deadline of 26 October for the Pentagon to respond.

Crow, a former Army Ranger who served in Iraq and Afghanistan, sits on the House Armed Services Committee and the House Permanent Select Committee on Intelligence, and co-chairs the congressional Protection of Civilians in Conflict Caucus. His office released the letter publicly on Tuesday.

What the Strike Involved

According to reporting by The Washington Post, cited in the lawmakers' letter, six weapons launched from US Navy aircraft targeted a communications complex near the wedding venue in Kuhestak. One of those weapons reportedly missed its intended target. The victims, according to the letter, included a four-year-old boy and a 16-year-old boy, along with dozens of injured. The Pentagon has not publicly acknowledged responsibility for the strike.

'We demand urgent answers regarding the United States' role in this strike, why the strike proceeded given the clear risk of significant civilian harm, and what steps the Department is taking to prevent further civilian casualties in Iran,' the lawmakers wrote.

Earlier Strikes Also Questioned

The letter also raised concerns about two additional incidents. The first involved the Shajareh Tayyebeh Elementary School in Minab, struck on 28 February — the opening day of the war — where reports indicate 175 civilians, including 120 children, were killed. The Pentagon has neither publicly acknowledged responsibility nor released investigation findings for that incident, according to the lawmakers.

The second involved a youth sports hall in Lamerd, where 21 civilians, including seven children, were reportedly killed. The Pentagon has denied responsibility for the Lamerd strike.

Civilian Harm Safeguards Under Scrutiny

The lawmakers also criticised sharp reductions in Pentagon programmes designed to minimise civilian casualties. According to their letter, civilian harm mitigation personnel at US Central Command have reportedly fallen from more than 10 to just one full-time staff member. Staffing at the congressionally mandated Civilian Protection Centre of Excellence has declined from more than 30 to seven. The lawmakers argued these cuts weaken the military's capacity to identify civilian infrastructure and assess risks ahead of operations.

This comes amid sustained congressional scrutiny of the human cost of American military operations against Iran. In March, 121 House members had separately sought information on civilian casualties and military safeguards during the Iran campaign. The Pentagon at the time said an investigation had been initiated and its findings would be shared with Congress once completed. Vice President J D Vance previously expressed scepticism about reports of American responsibility for the wedding strike, while acknowledging the incident was under investigation.

US Central Command has maintained that the American military does not target civilians. With the Pentagon's response deadline set for 26 October, the coming days will test whether Congress can secure the transparency it is demanding.
