At least 12 people were killed, and dozens more were injured after heavy fog led to a slew of crashes on a highway in eastern Bulgaria. On Tuesday, Nov. 10, around 7 a.m. local time, dense fog impacted visibility for drivers on the A1 highway that connects Sofia, the country’s capital, and Burgas, located on the coast of the Black Sea, resulting in two major crashes on either side of the roadway, the Associated Press, Reuters and Deutsche Welle reported.
