Lana Marks, US ambassador to South Africa and longtime friend of Mr Trump, was advised of Iran’s plans, according to Politico. The political journalism outlet mentioned two anonymous sources, one of whom was “familiar with the issue”.
US officials warned that Ms Marks links to the President could have influenced Iran’s decision to target her.
Mr Soleimani was killed on January 3 along with at least 6 others following an air strike carried out by an American drone.
Ever since, Iran has considered several ways of reciprocating the attack.
The top general was largely considered a national hero in Iran.
However, to other countries, the leader of the Quds Force of Iran’s Revolutionary Guards Corps was seen as a powerful threat.
Thought the past two decades western powers as well as Israeli and Arab nations have tried to execute him.
President Trump effectively mandated his assassination citing his “highest” responsibility as “the defence of our nation and its citizens”.
During the televised statement, he said: “Last night, at my direction, the United States military successfully executed a flawless precision strike that killed the number-one terrorist anywhere in the world, Qasem Soleimani.

“For years, the Islamic Revolutionary Guard Corps and its ruthless Quds Force – under Soleimani’s leadership – has targeted, injured, and murdered hundreds of American civilians and servicemen.
“The recent attacks on US targets in Iraq, including rocket strikes that killed an American and injured four American servicemen very badly, as well as a violent assault on our embassy in Baghdad, were carried out at the direction of Soleimani.
“Soleimani made the death of innocent people his sick passion, contributing to terrorist plots as far away as New Delhi and London.”
Following the killing of Mr Soleimani, US secretary of state Mike Pompeo expressed his backing of the decision to carry out the attack.
