Good afternoon. Anthony Albanese on Friday confirmed that three Australians were on a US submarine that sank an Iranian warship. The prime minister maintained that Australian forces were in compliance with international law, and said: “No Australian personnel have participated in any offensive action against Iran.”

The Greens senator David Shoebridge was scathing of what he called an “extraordinary” claim, saying the sailors’ involvement made Australia “obviously, clearly, unambiguously, part of an illegal war”.
