Bolivia ? Soldiers arrested an opposition governor Tuesday on suspicion of directing a massacre of government supporters, as Bolivia’s political crisis prompted Washington to put the nation on an anti-drug blacklist and evacuate its Peace Corps volunteers.

Violent protests against President Evo Morales have swept Bolivia’s eastern lowlands, where opposition-controlled provinces are demanding a larger share of the country’s natural gas wealth and trying to block his attempts to direct resources to the long-suffering indigenous majority.

The arrest of Leopoldo Fernandez, governor of the remote Amazonian province of Pando, had seemed to jeopardize attempts to seek compromise after anti-Morales protesters ransacked government offices in Pando and three other eastern provinces last week.
