One of Amsterdam's main hospitals is evacuating all its patients after a burst water main caused flooding in parts of the building.

Wouter Bos, chairman of the board of the Free University Medical Center, says no patients are in danger, but they are being moved to other hospitals in the city and region as a precaution because water has damaged electrical and water supplies to the building.

Bos says some 500 patients have to be moved, including 12 infants.

Water inundated an area around the hospital in southern Amsterdam early Tuesday, flooding streets and parked cars.

Waternet, the company responsible for the Dutch capital's water supply, says in a statement it has shut off the water pipe and is working to pump water away from the streets.
