An icy storm blamed for at least 65 deaths in nine states spread snow and freezing rain across Texas all the way to the Mexican border, immobilizing communities unaccustomed to such cold, The Associated Press reported. Hundreds of airline flights were canceled, tens of thousands of electricity customers lost power and a 300-mile (485-kilometer) stretch of Interstate 10, a major east-west highway, was closed. More than 350 flights out of Dallas-Fort Worth International Airport, San Antonio and Austin were canceled as officials worked to de-ice runways. Across the country, storms since Friday have cut off what had been an unseasonably mild winter in many areas. Ten deaths were blamed on the storm in Texas.
