Venezuelan officials say explosive drones went off as President Nicolás Maduro was giving a live televised speech in Caracas, but he is unharmed.
In a tweet, the president of Venezuela's National Assembly, Diosdado Cabello, called the incident at the military parade a "terrorist attack against the president and the high military command blaming the opposition for the violence".
He was standing next to his wife, Cilia Flores, and several high-ranking military officials.
While there was initial confusion as to what the footage actually showed, multiple sources have since reported that several drones "exploded" near the President while he was speaking.
Venezuelan President Nicolas Maduro, left, survived an "attack" during a ceremony to celebrate the 81st anniversary of the National Guard in Caracas on Saturday.
President Nicolas Maduro is blaming far-right factions in Venezuela for what he is describing as an assassination attempt.
The suspected attack on Maduro comes as his government struggles to deal with runaway inflation amid a failing economy.
The Associated Press could not independently verify the authenticity of message. The camera then cuts to the scene on the street, where soldiers and others in the crowd are seen running away from what may have been an explosion.
Last year, a rogue Venezuelan police officer hijacked a helicopter and fired at government buildings in what he said was an action against a dictator.
In the statement to el Nuevo, the group claiming responsibility said the military's goals were not achieved. The live television transmission was cut off without explanation. Perez was hunted down and killed by Venezuelan forces in January.
The attack comes as the nation struggles with an economic crisis.
