Oman, the mediator of nuclear talks between Washington and Tehran, has condemned US strikes on nuclear sites in Iran, calling it an “unlawful act of aggression”, Oman News Agency reports.

“The Sultanate of Oman denounces this unlawful act of aggression and urges immediate and comprehensive de-escalation,” according to a statement by a spokesperson for the foreign ministry.

“US action risks widening the conflict and constitutes a flagrant violation of international law and the United Nations Charter,” the statement added.

The spokesperson stressed that “ targeting nuclear facilities — prohibited under the Geneva Conventions due to the severe risks of radioactive contamination — further exacerbates the breach of global norms.“

“International law guarantees nations the right to pursue peaceful nuclear programs under the supervision of the International Atomic Energy Agency (IAEA),” the statement read.
