The Venezuelan government has begun releasing detainees considered political prisoners by human rights groups, in what officials described as a goodwill gesture, BBC reported.
Spain's foreign ministry said five of its nationals, including one dual national, had been released. Among them is thought to be rights activist Rocio San Miguel.
The move comes after the US took Venezuela's President Nicolas Maduro in a lightning raid on the capital, Caracas, on Saturday, to face drug trafficking charges in New York, according to BBC.
