Six people have been arrested in Venezuela for involvement in an apparent assassination attempt on President Nicolás Maduro, the interior minister says.
Nestor Reverol said they were part of a group that loaded two drones with explosives and set them off during a military parade in the capital Caracas.
Maduro has warned the perpetrators face "maximum punishment".
He has blamed Colombia for the incident but provided no evidence.
Colombia said the accusation was "baseless".
The government has also pointed the finger at the opposition, prompting fears of a new crackdown.
Many opposition leaders have already left the country citing government harassment and there are reported to be more than 200 political prisoners in the country's jails.
Maduro was speaking at a military ceremony when the incident happened.
