Winter Weather Hits Parts of Europe, From Poland to Turkey

Extreme cold has hit large parts of Europe, with freezing temperatures cracking railroad tracks in Poland, snow blanketing the Turkish city of Istanbul and smog spiking as coal was being burned to generate heat. Temperatures dropped to minus 28 degrees Celsius (minus 18 Fahrenheit) in some Polish areas overnight, the coldest night in 11 years. Many trains were delayed on Monday after rail tracks at two Warsaw railway stations cracked. Hand-in-hand with the cold came a spike in smog in Warsaw and other parts of Poland, as the cold prompted an increase in burning coal for heat.
