Lightning strike injures 11, including 8 kids

11 people including eight children have been hit by lightning in a Paris park after a sudden spring storm overtook a child's birthday party.

According to the the city's fire service, the victims had sought shelter Saturday under a tree at Park Monceau, a popular weekend hangout for well-to-do families in Paris.

Spokesman Eric Moulin says six of those hit were seriously injured, including four children and two adults. He said a further five people were slightly injured, including four children and another adult. The children were all around nine years old.
