Three patients died in a hospital fire in Austria, which caused the evacuation of about 90 patients, a spokesman for the institute located in Mödling, south of Vienna, told AFP.

"The cause of the disaster cannot yet be determined with certainty," the spokesman said. The fire broke out around one a.m. in a hospital center room and spread rapidly, according to a press release from the regional health agency.

Firefighters dispatched 33 vehicles and about 170 men to the scene. A Red Cross team also intervened. The fire was brought under control after two hours and the patients, unharmed, were transferred to other hospitals. An investigation has been opened.
