The U.N. nuclear watchdog's 35-nation Board of Governors overwhelmingly passed a resolution criticising Iran for failing to explain uranium traces found at three undeclared sites, diplomats at a closed-door meeting said on Wednesday.
Only two countries, Russia and China, opposed the text while 30 voted in favour and three abstained, the diplomats said.
The text says the board "expresses profound concern" the traces remain unexplained due to insufficient cooperation by Iran and calls on Iran to engage with the watchdog "without delay".
