Trump says Russia pulled its people from Venezuela

US President Donald Trump said on Monday that Russia told the United States it had removed most of its people from Venezuela.

The United States backs opposition leader Juan Guaido as the legitimate leader of Venezuela and has stepped up economic sanctions to help drive President Nicolas Maduro from power.

Russia supports Maduro, who has said Guaido is a puppet of Washington.

"Russia has informed us that they have removed most of their people from Venezuela," Trump, who is on a state visit to Britain, wrote on Twitter. He did not elaborate.

Early last month Trump said he focused on humanitarian aid for Venezuelans during a phone call with Russian President Vladimir Putin.

Most other Western countries also support Guaido, who invoked the constitution in January to declare himself interim president, arguing that Maduro's 2018 re-election was illegitimate.
