Mediation helping resolve crisis: Morales

Bolivian President Evo Morales says mediation by South American leaders is having a positive effect in a political crisis between his central government and eastern provinces demanding greater autonomy.

The 12-nation Union of South American Nations is pledging to help prevent political collapse in Bolivia, after deadly protests swept eastern Bolivia this month as anti-Morales groups blockaded highways, sacked government offices and seized gas pipelines.
