Leaders of the Mercosur trade bloc agreed not to slap economic sanctions on Paraguay after the ousting of its president because they felt it would hurt the Paraguayan people. Mercosur leaders criticized the impeachment and barred ousted President Fernando Lugo's replacement, former Vice President Federico Franco, from attending the summit. (AP Photo/Natacha Pisarenko)
