Watch: Marble-size hailstones and thunderstorms hit Paris

Marble-size hail was seen pelting Paris' streets, while cars were damaged by trees felled by lightning on Saturday afternoon.

Minor flooding also led to Metro stations being temporarily closed, according to local reports.

Thunderstorms are expected across parts of southern Europe this week, including southern areas of France, but there is a chance they could start spreading north again later in the week.
