Venezuelan Vice-President Elías Jaua promised that the national government is to investigate into alleged sabotage of the electricity grid last weekend in eastern Anzoátegui state and Caracas.

"We are going to investigate together with intelligence bodies into yesterday's events in Palo Verde (eastern Caracas) and what is happening in Barcelona and Puerto La Cruz (Anzoátegui state), where we have almost 15 days of continued outage and blasts in substations."

"Electricity grids are highly vulnerable and can be easily sabotaged, because anything can look like an electrical failure. Anything can create a short circuit," Jaua said.
