**Nikki Haley warns Iran of ‘severe consequences’ if it attacks US interests**

Former UN Ambassador says the US will not tolerate aggression from Tehran

Haley's comments come after a series of threats from Iran in response to the killing of Qasem Soleimani

Former US Ambassador to the United Nations Nikki Haley has warned Iran of "severe consequences" if it attacks US interests.

Haley's comments came in an interview with Fox News on Sunday, in which she said that the US will not tolerate aggression from Tehran.

"The Iranian regime is a threat to the United States and to our allies in the region," Haley said. "We cannot allow them to continue their aggressive behavior without consequences."

Haley's comments come after a series of threats from Iran in response to the killing of Qasem Soleimani, the head of the Iranian Revolutionary Guard Corps' Quds Force, in a US airstrike in Baghdad on January 3.

Iran has vowed to avenge Soleimani's death, and has threatened to target US interests in the region.

The US has deployed additional troops to the region in response to the threats, and has warned Iran that it will not tolerate any attacks on its interests.

The situation between the US and Iran remains tense, and there is concern that the two countries could be on the brink of war.
