The commander of Iran's Revolutionary Guard has warned that his forces are "more ready than ever" as U.S. warships move toward the Middle East. Tensions between Iran and the U.S. remain high following a crackdown on protests that began in December. Activists report over 40,000 arrests and a rising death toll. President Donald Trump has warned Iran against executing protesters and has moved warships "just in case." The situation has led some European airlines to suspend flights to the region. The U.N. has expressed concern over potential executions of detained protesters.
