Russians brave the ice cold waters of the Lena river in Yakutsk, eastern Siberia, generally considered to be the world's coldest city. The plunge is in celelbration of Orthodox Epiphany and has gone ahead despite local weather services warning that temperatures could sink as low as -62°C in some remote areas. "The feelings are always wonderful, it's always a feeling of purity - wonderful sensations - of warmth, " says pensioner, Irina Korsakova.
