A storm that swept through western Germany on Friday has killed at least one person and injured dozens, local authorities said Saturday.

In Rhineland-Palatinate state, a 38-year-old man died after he was electrocuted when he entered his flooded basement, the police in the city of Koblenz said.

In North Rhine-Westphalia state, authorities said a "tornado" wrecked the city of Paderborn, injuring 43 people, including 13 seriously, the city's mayor said Saturday.
