In the above text, it says that after US National Security Adviser, John Bolton left Turkey in mid-January (he was kicked out by Erdogan), and after making threats of war against Iran that his comments: "... were reportedly denounced through US embassies around the world". It says "reportedly" because the report appeared briefly on al-Jazeera only to quickly disappear. Now you never know but the report could well have been completely false, an invention from cyberspace yet, though the report couldn't be retrieved, it had a ring of authenticity about it.
A couple of days ago, in a written statement to the US Senate, US head of intelligence, David Coats, openly and comprehensively contradicted the views of Bolton and Secretary of State Pompeo over Iran, saying that the latter was limiting its activities to the JCPOA nuclear agreement and nor was it undertaking any key nuclear weapons development. In my opinion this is where the denunciation of Bolton's Iran comments came from and was relayed, through a coordinated process via US embassies, to the intelligence services of US allies around the world.
Coats also said in his statement that North Korea was unlikely to give up his nuclear weapons given the clout it gave to Kim Jong-un and further criticised Trump's policies over climate change, a major concern for US intelligence and the Pentagon.
What this underlines is the article's insistence on the convulsions currently hitting the US administration where significant departments are fighting one another - the intelligence services and Bolton's increasingly powerful National Security Council that is based in the White House.
