The crisis has been brewing in Venezuela for over a month, as Washington has backed opposition leader Juan Guaido, who unilaterally declared himself Venezuela's "interim president."

US President Donald Trump on Tuesday extended the sanctions against Venezuela for another year, which were imposed on the country's officials under former President Barack Obama in 2015, according to POTUS' declaration sent to Congress.

The document reads that the situation in Venezuela continues to "unusual and extraordinary" threat to the national security and foreign policy of the United States.

"For this reason, I have determined that it is necessary to continue the national emergency declared in Executive Order 13692 with respect to the situation in Venezuela."

The Executive Order, issued by President Barack Obama on March 8, 2015, imposed sanctions on seven Venezuelan officials over human rights abuses and corruption. Trump's decision extends the measure for another year.
