Canada’s foreign minister, Melanie Joly, has ordered her officials to summon Russia’s ambassador in Ottawa, Oleg Stepanov, over a series of “hateful” anti-LGBT tweets, including one aimed at an openly lesbian federal minister. The Russian Embassy posted the messages on Twitter in recent days after Russian lawmakers approved a bill banning all forms of LGBT “propaganda” that critics say ramps up a crackdown on “nontraditional” sexual relationships, affecting everything from books and films to social media posts.
