Iran's foreign ministry criticized US Secretary of State Mike Pompeo over his allegation that Iranian diplomats were behind the killing of an Iranian dissident in Turkey last November. 'Undisputed fact: US 'diplomats' have long been in the business of coups, arming terrorists,' ministry spokesman Abbas Mousavi said on Twitter on Saturday. 'But @SecPompeo ... and his masters have taken the 'job' to a whole new level.'
