A senior United Nations humanitarian chief has launched a blistering attack on Donald Trump, accusing him of treating the war with Iran like “a game show” while civilians face mounting devastation.

Tom Fletcher warned that attacks on infrastructure and threats to destroy Iran’s remaining facilities risk violating international law and pushing the region deeper into crisis.

UN Warns Civilian Targets Cross a Legal Line

Fletcher condemned strikes on bridges and other infrastructure, calling such attacks potential war crimes.

“You don’t hit civilian infrastructure — hospitals, schools, power sources, bridges,” he said in a broadcast interview. “War is not a game show; peace-making is not a real estate deal.”

Humanitarian agencies say the damage is already rippling across Iranian communities, leaving civilians to cope with power outages, supply shortages and growing economic turmoil.

Trump Threatens More Destruction

The criticism follows remarks from Trump threatening even broader attacks if Tehran refuses US demands.

Posting online, the president warned that American forces had “not even started destroying what’s left in Iran”, signalling bridges and power plants could be next.

The rhetoric has alarmed legal experts who say targeting infrastructure unrelated to military operations could breach international humanitarian law.

Legal Experts Raise Alarm

More than 100 international law specialists have signed an open letter expressing “profound concern” about the conduct of the conflict.

They argue the military campaign risks breaching the United Nations Charter, which restricts the use of force unless in self-defence or authorised by the Security Council.

Some experts also pointed to the reported bombing of a school in Minab during the war’s opening hours — an incident the United States Department of Defense says it is investigating.

Energy Crisis Fuels Global Tension

The war has already shaken global markets after Iran tightened control over the Strait of Hormuz, through which roughly a fifth of the world’s oil passes.

Governments fear prolonged disruption could trigger a major energy shock.

Meanwhile the United Kingdom and European partners are pushing diplomatic pressure to reopen the shipping lane.

Allies Split as War Escalates

Tensions have also emerged between Washington and London.

Trump mocked Keir Starmer for refusing to join the offensive, deriding Britain’s aircraft carriers as outdated.

British officials insist their priority remains avoiding escalation while keeping global trade routes open — a balancing act growing harder by the day.

Trump has no concept of what war means. Netanyahu revels in it.
