US investigating strike on Iranian wedding that killed at least four people

The United States is investigating a September 1, 2026, airstrike that hit a wedding celebration in the southern Iranian town of Kuhestak, killing five civilians and wounding nearly 70. While U.S. Vice President JD Vance announced a full investigation, independent weapons experts analyzing visual evidence concluded the damage was a direct hit from a U.S. guided munition. The strike occurred during a major escalation of the U.S.-Iran war, which has driven Brent crude oil prices over $96 a barrel and increased domestic political pressure on the Trump administration ahead of the November midterm elections.
