Madonna 'devastated' by death during concert construction

(CNN) - Madonna was "devastated" to hear that a man was killed in an accident during construction for her upcoming concerts in Marseilles, France, a representative said Thursday.

A 53-year-old French man was killed when a crane collapsed, a fire department spokesman in the southern French city said.

Another two people, one British and one American, are severely injured, and four are lightly injured, officer David Goddin told CNN.

"At this point we don't know how it happened, but we are confident no one else is still under the rubble," Goddin said.

"My prayers go out to those who were injured and their families along with my deepest sympathy to all those affected by this heartbreaking news," Madonna said in a statement issued by her representative, Liz Rosenberg.

At least one Madonna show has been canceled, Rosenberg told CNN.
