What happened
The record, in order.
On 14 April 2026 Iran's government spokeswoman Fatemeh Mohajerani told RIA Novosti that direct and indirect damage since 28 February was about USD 270bn, "an early estimate" given with no breakdown. Damage to oil and gas facilities, petrochemical plants, power plants and "water desalination plants" was still being assessed, and compensation "will be raised in any potential future talks with the US and mediators". Mohajerani also said "existing economic realities" meant the government could not repay civilians whose homes were damaged. The same day Iran's UN envoy said five regional countries must pay compensation (Al Jazeera, 15 April 2026).
On 11 October 2026 Foreign Minister Abbas Araghchi spoke at a conference on ecocide at Iran's Department of Environment in Tehran (Jamaran, 12 October 2026). He referred to the black rain that fell on Iranians, called for environmental protection to include "responsibility and compensation" without naming sums, and named COP31 as a venue to raise the issue. He said UNEP "confirmed" that the Tehran oil fires released compounds that could contaminate soil, water and the food chain.
UNEP's statement of 13 March 2026, as quoted by Human Rights Watch, said: "Heavy smoke from burning oil, which includes hazardous compounds, is now being directly inhaled by people in Iran". No environmental sub-total of the USD 270bn has been published.
