Iran has stopped dismantling centrifuges in two uranium enrichment plants, state media reported on Tuesday, days after conservative lawmakers complained to President Hassan Rouhani that the process was too rushed.

North Korea said on Tuesday its main nuclear complex was operating and it was working to improve the "quality and quantity" of weapons which it could use against the United States at "any time."

The United States tried to deploy a version of the Stuxnet computer virus to attack North Korea's nuclear weapons program five years ago but ultimately failed, according to people familiar with the covert campaign.
