Venezuela’s opposition leader has told the BBC that people are living in a “dictatorship” and renewed his calls for fresh elections.
Juan Guaidó declared himself interim leader last week and has been recognised by more than 20 countries, including the US.
President Nicolás Maduro retains the support of Russia, which has accused the US of “illegal” interference.
At least 40 people are believed to have died in recent unrest, the UN says.
Protests have been growing since Mr Maduro began a second term as president this month. He was elected last year during a controversial vote in which many opposition candidates were barred from running, or jailed.
Venezuela has been struggling with a massive economic crisis. Hyperinflation and shortages of essentials such as food and medicine have forced millions to flee the nation.
Speaking to BBC Mundo in Caracas on Monday, he defended his claim to be interim leader.
Mr Guaidó said the Venezuelan constitution allowed him, as the head of the National Assembly, to take power when the president was considered to be illegitimate.
