Bulgaria

Across Europe, young men dive into ice-cold waters to celebrate the Christian Orthodox feast of the Epiphany, the baptism of Jesus, while in Kalofer, Bulgaria, they perform the “ice ring dance”.

As at least four people are killed in an explosion on a bus carrying Israeli tourists in Bulgaria, the Israeli prime minister blames Iran for the attack.

Eastern parts of Europe are in the grip of a severe cold spell that has killed dozens of people, with temperatures dipping below -20C.
