Heavy rains flooded huge parts of northern Europe over the weekend as "freak thunderstorms" ravaged the continent and left as many as five people dead.
In Poland, one man was struck dead by lightning. In Germany, two men were presumed dead after being sucked into a flooded underpass, and two others perished in flood-related accidents. Dozens were injured in lightning strikes at a children's birthday party in Paris and a soccer match in Germany.
