U.N. says humanitarian crisis unfolding in Ethiopia; Iran warns U.S.
The U.N. said more than 27,000 people have fled Ethiopia into neighboring Sudan as fighting continues in Ethiopia's Tigray region. Also, Iran's government issued a stark warning to the U.S. over reports that President Trump asked advisers for options on striking Iran's main nuclear site, and a delegation from Bahrain touched down in Israel on the first direct commercial flight between the two countries. CBS News foreign correspondent Ian Lee joined "CBSN AM" from London with those headlines and more.
