Trump Warns Iran: "We Have an Armada"

President Donald Trump says a powerful U.S. naval force is moving toward the Middle East. He stated the ships are being sent "just in case" of conflict with Iran. Trump made the comments while returning from the World Economic Forum in Davos. He said the United States is watching Iran "very closely" but hopes military action will not be needed. The warning comes as activists report a rising death toll in Iran. They say more than 5,000 people have been killed in the government's crackdown on recent protests.
