Iranian scientists linked to the regime reportedly traveled to Russia in late 2024 to advance nuclear weapons research, according to a Financial Times investigation. The meetings, organized by a front group for Iran's military research organization, involved Russian military experts and representatives from a sanctioned laser technology company. This was the second such visit in 2024, with further meetings taking place in Tehran in early 2025 involving Russian technical experts and Iranian officials. Western officials and analysts say these interactions provide strong evidence of high-level cooperation between Russia and Iran on nuclear weapons-related research.
