The "Beast from the East", an unusually cold bank of weather, heads to the UK, leaving a chill of icy devastation to its flank.
Air bubbles settle under a frozen lake, a humpback whale beaches itself near the French city of Caen, and a Palestinian demonstrator returns a tear gas canister towards Israeli soldiers.
Finally, a cyphotilapia frontosa swims in its tank at the Aquarium of the Berlin zoo.
It's pictures of the day.
