Caracas, April 6 (teleSUR-RHC)-- A petition launched in Venezuela opposing President Barack Obama’s latest sanctions and the labeling of Venezuela as a national security threat to the U.S. has topped eight million signatures, it was announced on Sunday.

President Obama issued an executive order on March 9 announcing a “national emergency with respect to the unusual and extraordinary threat to the national security and foreign policy of the United States posed by the situation in Venezuela.”

Venezuelan President Nicolas Maduro thanked supporters who backed the call for Obama to "repeal the decree” through his Twitter account. The signatures will be handed in during the Summit of the Americas which starts later this week in Panama and will be attended by all the nations in the hemisphere.

Mounting hostility by the U.S on Venezuela is likely to be one of the most debated issues at the Summit, which U.S. President Barack Obama is expected to attend.

Additionally, millions have taken Twitter to express their opposition to the U.S. aggression. It was revealed last week that at least five million tweets across 105 countries have demanded a repeal of the measures.
