Legal experts warn US role in war raises risk of international law violations More than 100 US-based international law experts have warned that the US-Israeli war on Iran raises “profound concern” over potential violations of international law. In a letter published by the Just Security Forum, the signatories said the campaign may breach the UN Charter and raised concerns about possible violations of human rights and humanitarian law, including potential war crimes. The letter pointed to growing civilian harm, environmental damage and wider regional risks. It also criticised US officials’ focus on “lethality”, warning such rhetoric could undermine global norms protecting civilians.
