A Venezuelan opposition lawmaker sought refuge at the Argentine Embassy in Caracas on Thursday, according to an Argentine foreign ministry source and a Reuters witness, a day after the arrest of a top figure in the opposition-controlled legislature.

Richard Blanco of the Brave Peoples¡¯ Alliance party had entered the embassy on Thursday morning, said the Argentine official, who asked not to be identified. ¡°He (Blanco) is there as a guest, we can confirm that,¡± the official said.

On Wednesday, Edgar Zambrano, the opposition-run National Assembly¡¯s vice president, said he had been arrested by intelligence agents.
