A federal court is blocking a joint "truth commission" Argentina's government set up with Iran to investigate the 1994 bombing of the Argentine-Israeli Mutual Association in Buenos Aires, but officials say they will appeal. A federal court ruled Thursday night that Argentina Foreign Minister Hector Timerman exceeded his authority in reaching the deal. The attack killed 85 people, but despite 20 years of trying, Argentina's justice system has yet to bring anyone to trial. Top Iranian officials have been on an Interpol capture list for years, but Argentine prosecutors have never been able to question them. Timerman said Friday that Argentina's judicial branch is invading an area of clear executive power. Cabinet Chief Jorge Capitanich said it is appealing and seeking a speedy final ruling from the country's Supreme Court.
