President Donald Trump threatened to commit genocide in Iran, ahead of warnings of a wave of attacks on civilian infrastructure on Tuesday night. “A whole civilization will die tonight, never to be brought back again,” he wrote on Truth Social on Tuesday. This followed a drumbeat of similar threats of wanton and criminal destruction. “The entire country could be taken out in one night. And that night might be tomorrow night,” he said on Monday, having recently warned he would bomb Iran “back to the Stone Ages.”

“President Trump has repeatedly threatened war crimes in Iran and now he is expressing genocidal intent,” said Sarah Harrison, an associate general counsel at the Pentagon’s Office of General Counsel, International Affairs during Trump’s first term. “Every single lawmaker and national security leader needs to stand against this and make clear to the U.S. military that these are unlawful orders and if carried out they will someday face criminal prosecution.”

This interpretation was echoed by Rebecca Ingber, a former State Department lawyer and now a law professor at Cardozo Law School. “The U.S. understanding of the definition of genocide in the Genocide Convention requires a ‘specific intent’ to destroy a group — such as a national or ethnic group as relevant here,” she told The Intercept. “That is an intentionally high bar, and one that explicitly would not cover unintended consequences of armed conflict. If acted upon, the President’s statement would be evidence of that required specific intent.”

Trump has repeatedly threatened to obliterate Iran’s civilian infrastructure should the nation’s leaders not heed his demands. “We have a plan because of the power of our military where every bridge in Iran will be decimated by 12:00 tomorrow night,” he said on Monday. “Where every power plant in Iran will be out of business, burning, exploding, and never to be used again.” This echoed an Easter morning missive. “Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. There will be nothing like it!!!” Trump ranted on Truth Social. “Open the Fuckin’ Strait [of Hormuz], you crazy bastards, or you’ll be living in Hell.”

Asked on Monday if he was concerned that his threat to bomb power plants or bridges amounts to war crimes, Trump replied “No, not at all,” and said in another interview, “I’m not worried about it.”

“What President Trump is describing as the destruction of ‘a whole civilization’ would be a war crime, plain and simple,” said Sarah Yager, the Washington director at Human Rights Watch and a former senior adviser on human rights to the chairman of the U.S. Joint Chiefs of Staff. “There is no gray area on this under international law.”

Civilian infrastructure has been a frequent target since the U.S.–Israeli war on Iran began on February 28. “Strikes on critical infrastructure and industrial sites have disrupted basic services including electricity, water and telecommunications, also leading to increasing immediate and longer term environmental and health risks,” wrote the U.N. Office for the Coordination of Humanitarian Affairs, or OCHA, in a brief report issued last week. Airports, cultural heritage locations, hospitals, industrial sites markets, residential areas, and schools have also been struck, including the civilian international airport in Tehran, a power plant in Khorramshahr, and water reservoirs in Fars and Khuzestan. Last week, the U.S. attacked the newly constructed B1 highway bridge, which killed 8 people, who were, according to the deputy governor of Alborz province, not military targets but nearby villagers celebrating Nowruz, the Persian new year.

The International Atomic Energy Agency has confirmed strikes affected multiple nuclear sites, including Iran’s Bushehr nuclear power plant. Rafael Grossi, head of the nuclear watchdog, warned on Monday that “continued military activity near the BNPP — an operating plant with large amounts of nuclear fuel — could cause a severe radiological accident with harmful consequences for people and the environment in Iran and beyond.”

Trump claimed that the Iranian people actually want the United States to attack their civilian infrastructure, citing “numerous intercepts” of communications. “‘Please keep bombing,’” Trump said on Monday of these supposed pleas. “And these are people that are living where the bombs are exploding. And when we leave, and we’re not hitting those areas, they’re saying, ‘Please come back.’”

In actuality, Iranians have been fleeing from Tehran and other major urban areas under attack. Almost a month ago, UNHCR — the U.N. refugee agency — reported that as many as 3.2 million people were already displaced inside Iran due to the conflict. While casualty counts are fragmentary, more than 2,100 civilians had been killed in the war by the end of last month and around 28,000 injured, according to Iranian Ministry of Health and Medical Education. This included 216 children killed and 1,881 injured, as of April 3.

Yager noted that Iranians who have already suffered severe government repression, including the mass killings of protesters earlier this year, now face obliteration by America. “They’re being told their entire society could be destroyed by the president of United States, with the power of the U.S. military at his fingertips. His previous threats to bomb their power plants and bridges are threats to the systems that keep people alive, their electricity, water, and health care,” she told The Intercept. “Even before anything happens, that kind of rhetoric creates deep anxiety and fear for millions of civilians who have no control over these decisions but who will bear the consequences.”

Almost 115,200 civilian homes, commercial properties, and other civilian sites have been damaged in the war, according to the Iranian Red Crescent Society. This includes 763 schools. The highest profile of these strikes was the U.S. attack on the Shajarah Tayyebeh elementary school. The attack killed around 175 civilians, most of them children. A preliminary Pentagon report concluded the strike was conducted by U.S. forces, directly contradicting assertions by Trump that Iran struck the school.

The Iranian Red Crescent also reported that more than 334 medical, health, pharmaceutical, and emergency centers have been damaged, including 18 of its own centers. Twenty-four health workers have been killed and 116 injured, according to Iran’s Ministry of Health and Medical Education.

Around 400,000 people are also facing food insecurity in Tehran alone, according to local authorities. Inflation for groceries is at almost 113 percent, severely curtailing people’s purchasing power, according to OCHA.
