CARACAS, Aug. 22 (Xinhua) -- Venezuela is seeking the extradition of nine nationals allegedly involved in a recent reported "failed assassination attempt" against President Nicolas Maduro, a top official said on Wednesday.

The suspects are Venezuelan nationals currently living in the United States, Colombia and Peru, Prosecutor General Tarek William Saab said during a press conference.

"We expect these countries to cooperate because the fight against terrorism has no borders," he said.

The number of people linked by the authorities to the Aug. 4 attack has climbed to 43. To date, 21 have been charged formally. Saab said both the people responsible for carrying out the attack as well as those who provided financial and logistical support have been identified.

The assassination attempt reportedly took place in Caracas as Maduro was giving a military speech. Two drones packed with explosives flew toward the presidential stand and detonated. While Maduro escaped injury, several soldiers were injured, the authorities said.
