Representatives of Venezuelan opposition leader Juan Guaido have taken control of three of the country's diplomatic properties in the United States, Guaido's U.S. envoy said on Monday, as the opposition presses its bid to oust socialist President Nicolas Maduro.

The envoy, Carlos Vecchio, said the opposition had gained control of two buildings belonging to Venezuela's defense ministry in Washington and one consular building in New York. He added that the group expects to take control of Venezuela's embassy in Washington "in the days to come."

The moves come after Guaido, the president of the opposition-controlled National Assembly, invoked the constitution to assume an interim presidency in January, arguing that Maduro's May 2018 re-election was illegitimate. He has been recognized as Venezuela's rightful leader by most Western countries, including the United States.
