Iran turned off two surveillance devices Wednesday used by UN inspectors to monitor the country's uranium enrichment, further escalating the crisis over its atomic program as Tehran's nuclear deal with world powers remains in tatters.
The move appeared to be a new pressure technique as Western nations seek to censure Iran at a meeting this week in Vienna at the International Atomic Energy Agency. The censure deals with what the watchdog refers to as Iran's failure to provide "credible information" over nuclear material found at undeclared sites across the country.
