Oil prices are up about 2% on Wednesday after Iran's security chief, Rezaei, said Tehran would not let enriched nuclear material leave the country, Reuters reports via Dawn. That is double the gain of about 1% that Dawn logged around midday UK time on the same remarks.
Reuters says the comments added to supply worries that had already lifted prices off Tuesday's two-month lows. Earlier on Wednesday, Brent had risen 1.1% to $92.53 a barrel.
No price level has been reported alongside the latest rise, so the 2% figure has not been independently checked.
Dawn adds that Washington says nuclear issues must be part of any initial negotiations with Tehran.
