Authorities in Venezuela say 12 people were killed overnight following looting and violence in the South American nation's capital amid a spiraling political crisis.

The Public Ministry confirmed the deaths Friday and said another six were hurt.

Most of the deaths took place in El Valle, where opposition leaders say 13 people were hit with an electrical current while trying to loot a bakery protected by an electric fence.

Tens of thousands of people opposed to Venezuela's socialist government took to the streets on Thursday in ongoing protests demanding elections and denouncing what they consider an increasingly authoritarian government. They were met by tear gas and rubber bullets as they tried to march to downtown Caracas.
