Norwegian authorities have pressed charges against a professor for violating sanctions on Iran between 2018 and 2019. The professor invited four Iranian researchers to a university in Trondheim, where he gave them access to the "nano-mechanical lab", which can analyze metal alloys. One of the Iranian researchers allegedly installed software on a computer system that allowed him to continue to collect data without university credentials. Norwegian prosecutors said that the knowledge had the potential to be useful to Iran's nuclear program. The professor, a German-Iranian dual citizen, has left Norway but is willing to return for court proceedings, according to his attorney.
