CARACAS -- Several Venezuelan political figures on Saturday strongly condemned US aggression and called on the public to remain calm and alert.

Venezuela's Vice-President Delcy Rodriguez, speaking on a state-run television station, said the whereabouts of President Nicolas Maduro and his wife were unknown, asking for proof they are alive.

She added that the US military aggression caused the deaths of many Venezuelan military personnel and civilians in the capital Caracas, as well as in the states of Miranda, Aragua and La Guaira.

No external government or external force should attempt to give orders to Venezuela, nor should they try to dominate the Venezuelan people, she stressed, adding that the US act violates the South American nation's sovereignty, undermines peace and tranquility, and claims the lives of innocent Venezuelans.

"They made a sneaky, vile attack on sleeping people. They cowardly attacked the people," Venezuelan Interior Minister Diosdado Cabello said, condemning the US attack on Caracas.

He urged the public to remain calm, calling for letting no one "fall into despair" or "fall into making things easier for the invading enemy, the terrorist enemy who attacked us cowardly."

Tarek William Saab, attorney general of Venezuela, said the US government should be held responsible for what could happen to Maduro and his wife.

"I strongly condemn the vile and cowardly attack by the imperial enemy, carried out in the early hours of the morning against civilian and innocent targets of our homeland," he said.

This fact shows that what the Venezuelan president had warned about has now turned into acts of blood, he added.

He also urged the public to remain calm and alert, without falling into the "enemy's psychological warfare."
