Justin Trudeau criticized Vladimir Putin but when asked whether he also had concerns about Donald Trump's defence of Putin, he refused to say.

Social networking site Twitter on Saturday suspended two accounts linked to 12 Russian spies indicted by Special Counsel Robert Mueller for interfering in the 2016 U.S. presidential election.

Putin said Russia will "never" extradite any of the 13 Russians indicted by the U.S., even as he insisted they didn't act on behalf of his government.
