US Ambassador to the UN Nikki Haley said that Iran's ballistic missile test on Sunday was unacceptable.
"I will tell the people across the world that is something you should be alarmed about," Haley told reporters Tuesday after the UN Security Council's consultations on Iran.
"The United States is not naive," she added. "We are not going to stand by. You will see us call them out, as we said we would, and you are also going to see us act accordingly."
