EU and Iranian officials met for a second day of talks Sunday, hoping to build on reported progress in efforts to reconcile Tehran's refusal to freeze uranium enrichment with international demands that it do so or risk U.N sanctions. Sunday's talks began between aides to Iran's chief nuclear negotiator Ali Larijani and EU foreign policy chief Javier Solana, both of whom joined the talks later in the morning, the Associated Press reported. The two sides said talks Saturday had been «constructive.» Being held at the Austrian chancellor's office, the meeting has been billed as possibly the last chance for Iran to avoid penalties for rejecting the U.N. Security Council's demand that it stop enriching uranium. On Saturday, Larijani spoke of «good and constructive talks, and ... some progress in some areas,» while Solana's spokeswoman, Cristina Gallach, described them as «constructive and positive.»
