Madonna on Sunday visited some of the eight workers who were injured in an accident in which two more were killed while assembling a music stage for the singer in the French port of Marseilles.

Madonna's concert that was scheduled for Sunday night in Marseilles was canceled after the accident Thursday at the Velodrome stadium. The roof of the stage collapsed while it was being built and crashed down on the workers.

The next stop on her tour is in Barcelona, Spain on Tuesday.
