It has been revealed that the Iranian government was considering assassinating Lana Marks, the American ambassador to South Africa. With tensions between the United States and Iran mounting, this new information will likely usher in a new phase of escalation.

Politico.com broke the story late Sunday citing U.S. intelligence reports and statements from an unnamed U.S. government official familiar with the situation. The story was confirmed by another official who has seen the intelligence. According to a U.S. government official, the Iranian Embassy in Pretoria is involved in the assassination plot.

There are also reports that Iran is targeting the U.S. Ambassador to South Korea, Harry B. Harris. 

If the information is accurate, this would be a major escalation of the ongoing conflict between the two countries.

According to the intelligence in the report, Iran has been planning on taking out Marks for months. But intelligence operatives found that the threats had in recent weeks become more “specific.”

According to the report, the intelligence community issued a directive known as “Duty to Warn” which requires U.S. intelligence agencies to notify a potential target if intelligence indicates their life could be in danger. Marks has been made aware of the threat and the government is taking precautionary measures.
