BOGOTÁ, Colombia — Jorge Ramos, a news anchor for the television network Univision, said he was detained by the Venezuelan government during a confrontational interview with President Nicolás Maduro on Monday evening at the Miraflores Palace in Caracas.

“He didn’t like the things we were asking him about the lack of democracy in Venezuela, the torture and the political prisoners,” Mr. Ramos recounted on a Univision broadcast, after he said he was released by the government.

Mr. Ramos said he had been detained for “more than two hours” before he was let go and allowed to return to his hotel. He said the government had confiscated his crew’s equipment, including their phones and memory cards.

“We don’t have anything,” he said. “They have the interviews.”

On Monday night, Kimberly Breier, the assistant secretary of state for the Western Hemisphere at the State Department, said that Mr. Ramos had been detained and called on the government to release him immediately.
