CARACAS, Venezuela -- Authorities detained six people suspected of using explosives-laden drones in a, officials said Sunday. Interior Minister Nestor Luis Reverol on Sunday described it as a terrorist attack and said more arrests could follow within hours. Investigators have raided hotels and seized vehicles for details into the plot.
Venezuela's socialist government alleged Sunday that the detained suspects conspired with others in Miami and the capital of neighboring Colombia, though they offered no specific evidence. Opposition leaders criticized Maduro for broadly singling out his political opponents, and they warned that he might use the attack to further suppress his critics.
Thecomes as Venezuela is reeling from a and Maduro has grown increasingly isolated. Foreign nations, including the United States, are slapping economic sanctions against a growing list of high-ranking officials and decrying his government as an autocratic regime.
Maduro and his allies called the attack direct proof that an international plot to overthrow his socialist administration exists, while also saying that the military's response shows he still has the loyalty of Venezuela's soldiers.
But analysts said the images broadcast live on television when the attack struck during a Maduro speech Saturday evening made him appear vulnerable.
"Seeing trained soldiers fleeing in apparent panic and disarray before an explosion strongly contrasts with the idea of monolithic control and loyalty of security forces that Maduro prides himself on," the New York-based Torino Capital investment firm said.
The assailants flew two drones each packed with 2.2 pounds of C-4 plastic explosive toward Maduro, his wife and other top leaders as he spoke Saturday evening at an event celebrating the 81st anniversary of the National Guard, Reverol said. One of the drones was to explode above the president while the other was to detonate directly in front of him, he added.
But the military managed to knock one of the drones off-course electronically and the other crashed into apartment building two blocks away from where Maduro was speaking to the hundreds of troops, Reverol said.
"We have six terrorists and assassins detained," Reverol said. "In the next hours there could be more arrests."
Of those arrested, Reverol said two had previous run-ins with the government, although he did not give their names or say what charges they faced. One took part in 2014 protests that rocked the nation as it descended into an economic crisis that is now worse than the Great Depression. The other had a warrant out for his arrest for participating in an attack on a military barracks.
Defense Minister Vladimir Padrino Lopez, appearing on state television Sunday, said the attackers were aiming to decapitate Venezuela's entire top leadership along with Maduro.
Investigators continued searching a blackened apartment building near the site while also seizing vehicles and raiding more than one hotel where they said they had found "film evidence."
Two witnesses who live in nearby apartment buildings said they saw a drone hovering over a residential street Saturday evening and then heard an explosion.
One witness showed The Associated Press cellphone video of a drone crashing into a building. He said the drone fell to the ground and exploded, igniting a fire in an apartment.
Another witness, Mairum Gonzalez, described running in panic to her fifth-floor balcony, where she heard the second explosion and saw smoke rising.
"It was so strong the building shook," she said. "It terrified me."
In an address to the nation Saturday night, a visibly shaken Maduro recalled seeing a "flying device" that exploded. He at first thought it might be a pyrotechnics display.
Within seconds, Maduro said he heard a second blast and pandemonium broke out. Bodyguards escorted him from the event, covering him in black shields, and TV footage showed uniformed soldiers break formation and scatter.
"This was an attempt to kill me," he said.
Maduro said the "far right," working in coordination with others in Bogota and Miami, including Colombian President Juan Manuel Santos, were responsible. Colombia's government has vehemently denied Santos had any role in the drone attack.
Maduro, who also says that Washington supports his political opponents, called on U.S. President Trump to hold the "terrorist group" accountable.
Mr. Trump's national security adviser John Bolton told "Fox News Sunday" that, "If the government of Venezuela has hard information that they want to present to us that would show a potential violation of U.S. criminal law, we'll take a serious look at it."
The Broad Front, a coalition of opposition groups in Venezuela, accused the government of making an allegation without proof.
"It's evident that the initial reaction of the government isn't aimed at attempting to clarify what happened but rather to take advantage of the situation and irresponsibly and sweepingly attack the 'opposition,'" the group said in a statement.
A little-known group calling itself Soldiers in T-shirts claimed responsibility for the attack, saying it planned to fly two drones loaded with explosives at the president but soldiers shot them down. The authenticity of the message could not be independently verified, and the organization did not respond to a message from the AP.
"It was not successful today, but it is just a matter of time," the group said in a tweet.
Venezuela's government routinely accuses opposition activists of plotting to attack and overthrow Maduro. The former bus driver has moved steadily to consolidate power as the nation struggles to reverse hyperinflation that the International Monetary Fund projects could top 1 million percent by year's end.
The firebrand leader sees his mission as carrying out the late Hugo Chavez's socialist revolution. He recently won a new term in office in a widely condemned election. The opposition's most popular candidates were barred from running.
Maduro said the incident had left him convinced of the military's support and undeterred in carrying forward the torch of Chavez's revolution.
"Venezuela will continue on the democratic, independent and socialist path," he said.
It was not the first time Maduro's government has come under attack.
Amid deadly, near-daily protests last year, a rogue police officer flew aat several government buildings. Oscar Perez and several comrades were later killed in a gun battle after over six months at large.
David Smilde, a senior fellow at the Washington Office on Latin America who has spent decades researching Venezuela, said Saturday's incident did not appear to be a staged attack by Maduro's government for political gain.
The "amateurish" attack prompted embarrassing images of Maduro cut off midsentence with droves of soldiers running away in fear, making the president appear vulnerable, Smilde noted. Despite the optics, Smilde said he suspected that Maduro would nonetheless find a way to take advantage of it.
"He will use it to concentrate power," Smilde said. "Whoever did this, he'll use it to further restrict liberty and purge the government and armed forces."
The event had been just one more of many Maduro routinely holds with members of the military, a key faction of Venezuelan society whose loyalty he has clung to as the nation struggles with crippling hyperinflation and shortages of food and medicine.
"We are going to bet for the good of our country," Maduro declared triumphantly moments before the explosion. "The hour of the economy recovery has come."
