Talks between Iran, Shell and Spain's Repsolover over the country's South Pars gas project have ended at the order of the country's oil ministry, Reuters has reported. The two firms have been accused of procrastinating on finalising their involvement in the field, which Iran shares with Qatar. Last month Iran extended a new two-week ultimatum to Royal Dutch Shell and Repsol after the expiry of a one-week ultimatum issued in April.
