Brussels, Jan 10, SPA -- Iran's resumption of research work on nuclear fuel violates an agreement with European Union countries to hold back from sensitive nuclear activities, an EU spokesman said on Tuesday. "It is considered a violation of the Paris agreement. These activities are clearly related to enrichment," Cristina Gallach, spokeswoman for EU foreign policy chief Javier Solana, said by telephone. "This is very much a step in the wrong direction. We are extremely concerned and consultations are taking place (within the EU) to coordinate a response." Tehran announced earlier its nuclear research centers had restarted their activities. --SPA 13 13 Local Time 10 13 GMT www.spa.gov.sa/318105
