A power blackout briefly darkened all of Venezuela's capital Monday night, and the government says other parts of the country also lost electricity.
Power started coming back on in Caracas within 10 minutes, and Electricity Minister Jesse Chacon later told state television that electricity had been restored to most of the city but was still out in several regions that he didn't identify.

While Caracas was dark people could be heard banging on pots — a frequent means of protest.
The energy minister said the blackout originated in central Venezuela, the same place that a power failure in September knocked out electricity to 70 percent of the country.
Although Venezuela has the world's largest proven oil reserves, it has been plagued by power outages in recent years.
