Venezuela’s government said on Monday it had suppressed a military revolt after a group of officers stole weapons and kidnapped several officials, as a video posted online showed a sergeant demanding the removal of President Nicolas Maduro.

Some two dozen officers attacked a National Guard outpost in the Caracas neighborhood of Cotiza, a kilometer (0.6 mile) from the presidential Miraflores palace, where they met “firm resistance,” the government said. Witnesses reported hearing gunshots at about 3 a.m. (0700 GMT).

Protesters later burned trash and a car outside the outpost, where the 25 officers were arrested, in a sign of growing tensions following Maduro’s inauguration to a second term that governments around the world have called illegitimate.

Though the incident signals discontent within the armed forces, it appeared to involve only low-ranking officers with little capacity to force change in the hyperinflationary economy as many people suffer from shortages of food and medicine.
