Iran fires ballistic missiles at two bases housing U.S. troops in Iraq

Iran's supreme leader says his country's revenge against the U.S. is not over after Iran's first military retaliation for the killing of General Qassem Soleimani. More than a dozen missiles were aimed at a base in Western Iraq and a base in Erbil, two of the sites where American troops are located. President Trump tweeted "all is well" after the attacks and boasted, "We have the most powerful and well-equipped military anywhere in the world, by far." Holly Williams reports from Baghdad.
