Venezuela's defence minister, Vladimir Padrino López, stated on Tuesday that if the opposition seeks to impose "a puppet government", it will have to pass over "our dead bodies."
He emphasised that state armed forces will continue being stationed along Venezuela's border to thwart possible territorial threats.
Commenting on the state of the country's senior military officers, the minister stressed that they remain "obedient and subordinate" to Venezuelan President Nicolas Maduro's government.
On 23 January, Guaido, who is the speaker of the opposition-controlled National Assembly, proclaimed himself interim president. He was almost immediately recognised by the United States and its allies. Russia, China, Mexico, among other nations, voiced support for constitutionally elected Maduro, who, in turn, accused Washington of orchestrating a coup in the country.
