Venezuelan authorities said they have suppressed a military rebellion near the central city of Valencia shortly after a small group of men dressed in fatigues released a video declaring themselves in rebellion.
The ruling Socialist Party's deputy, Diosdado Cabello, said there had been a "terrorist attack" at a military base.
His announcement came after a video emerged showing a group of men in military uniform saying they were launching an uprising against unpopular President Nicolas Maduro to restore democracy.
One witness in the area of the military base in the town of Naguanagua reported hearing gunshots before dawn, but Mr Cabello said the situation had been brought under control.
Troops acted quickly to control the situation at the Paramacay base in the central city of Venezuela, he said on Twitter.
