The White House has rejected a UN human rights report finding “reasonable grounds” to believe the United States committed war crimes in two strikes in Iran on February 28, including on a school in the southern city of Minab, Al Jazeera reports.

Spokeswoman Anna Kelly said the UN’s Human Rights Council has “accomplished nothing for human rights while spouting unserious nonsense for decades,” according to remarks carried by The Washington Post.

Kelly added, “The only party in this conflict that has committed war crimes is the Iranian regime.” The Trump administration has yet to acknowledge any responsibility for the attack on the school or release a Pentagon investigation into the incident.
