Super Fog Disaster on I-95: What went wrong

Humanitarian crisis in Ukraine

A humanitarian crisis is brewing in and around Ukraine. One million people – mostly women and children – have fled the country in the first week of Russia's invasion, according to the head of the United Nations refugee agency. The United Nations has predicted that upwards of four million people may eventually have to flee Ukraine. The one million people who have left so far account for about 2% of Ukraine's population.
