CARACAS, Oct. 18 (Xinhua) -- Venezuela's Communication and Information Minister Jorge Rodriguez on Wednesday announced new arrests in connection with the failed assassination attempt on President Nicolas Maduro in August.

Oswaldo Castillo alias "El Capi," Wilder Vasquez alias "Capo," and retired air force lieutenant colonel Rafael Diaz were arrested, Rodriguez said.

With these arrests, "the mastermind behind the assassination plot is perfectly established," said the minister, adding that those involved are associated with Venezuela's far right.

He said that these individuals also took part in violent protests from 2014 to 2017.

"We have now identified and captured the two groups who participated in the attempted assassination," Rodriguez said, noting the investigations will continue.

During an outdoor ceremony on Aug. 4 to commemorate the 81st anniversary of Venezuela's national guard, two drones carrying explosives flew close to the presidential stand as Maduro was giving a speech and detonated.

Maduro was unharmed but several members of the military sustained injuries.
