Venezuela’s President Nicolas Maduro is expelling three US consular officials, accusing them of meeting students involved in anti-government protests.
The country has seen growing political tension and rallies, with three protesters dying in clashes last week.
An arrest warrant has been issued for opposition leader Leopoldo Lopez, who has pledged to lead a march in the capital Caracas on Tuesday.
The US has expressed concern about arrests of opposition protesters.
Mr Maduro did not name the US officials being expelled, when he made the announcement in a national TV broadcast, but said the foreign ministry would give details later.
“It’s a group of US functionaries who are in the universities. We’ve been watching them having meetings in the private universities for two months. They work in visas,” the president said.
“Venezuela doesn’t take orders from anyone!” he added.
On Saturday, US Secretary of State John Kerry issued a statement expressing concern about the rising tensions in Venezuela.
“We are particularly alarmed by reports that the Venezuelan government has arrested or detained scores of anti-government protestors and issued an arrest warrant for opposition leader Leopoldo Lopez,” read the statement, BBC informs.
