9:55 p.m.

A Venezuela expert says it's likely President Nicolas Maduro will use a suspected assassination attempt to purge disloyal officials and further clamp down on liberties.

Authorities in Venezuelan said Saturday that drones loaded with explosives targeted Maduro speaking at a military celebration, but exploded before reaching the president.

David Smilde of the Washington Office on Latin America says the amateurish attack didn't appear to be staged by Maduro's government for political gain.

However, Smilde says it prompted embarrassing TV images of Maduro cut off mid-sentence with droves of soldiers running away in fear, making the president appear vulnerable.

Despite the optics, Smilde says Maduro will use it to concentrate power, further restricting liberty while purging the government and armed forces.

Venezuelan President Nicolas Maduro says authorities have captured some of those responsible for what he is calling an assassination attempt.

In an impassioned address to the nation, Maduro said some of the "material authors" of an attack with drones are now in custody.

He said far-right wing factions within Venezuela working in collaboration with conspirators in Bogota and Miami were responsible.

He did not provide the names of those detained or describe the charges they are facing.

Maduro added that some of those who financed the attack are in Miami and that he hoped President Donald Trump is "willing to fight the terrorist groups."

He promised a full investigation to hold all those responsible, "No matter who falls."

President Nicolas Maduro is blaming far-right factions in Venezuela for what he is describing as an assassination attempt.

In an address to the nation Saturday, Maduro said: "This was an attempt to kill me. Today they attempted to assassinate me."

He said evidence gathered thus far "points to the far right" working in conjunction with Colombians in the neighboring Andean nation.

Maduro said he believed Colombian President Juan Manuel Santos was also responsible.

He added police had made arrests in the incident but did not immediately provide any further details.

Colombians officials have not yet commented on the accusation. Santos has become one of Maduro's most outspoken critics.
