The story: Iran is said to be plotting to kill the US' ambassador to South Africa, amid escalating tensions between both countries since the US withdrew from a nuclear deal reached with multiple countries.
The details: According to reports, the threat against Marks is supposedly in retaliation for the US' killing of Iranian General Qassem Soleimani in January.
The background: The US claims that drone strike that killed Soleimani was never intended to do so, rather it was intended as a deterrent to Iranian aggression. In retaliation to the killing, Iran launched several rockets at US bases in Iraq, according to reports.
