Ecuador has declared a state of emergency in three provinces after a strike at state oil firm Petroecuador threatened to paralyze production.
Communications Secretary Enrique Proano says the provinces of Napo, Orellana and Sucumbios have been placed under military control to prevent further unrest.
It is the second state of emergency declared in the region in less than a month.
The emergency was declared after oil workers went on strike to demand back wages and better working conditions.
Petroecuador officials say angry workers have taken over the Auca oil installations in the Amazon jungle and shut down production.
