TAINAN, Taiwan (AFP) - A blaze tore through a Taiwan hospital for bed-bound seniors and mentally ill patients Tuesday, killing 12 and injuring 60, with police reportedly arresting a patient suspected of starting the fire. The fire erupted before dawn at Beimen nursing facility in south Taiwan’s Tainan city, whose 115 patients included people in their 90s, with several left on their own to escape dense smoke that filled the building. Local media said police had arrested a person believed to be a hospital patient on suspicion of starting the blaze . Police and prosecutors declined to comment. Closed-circuit TV footage taken moments after the blaze broke out showed hospital staff scrambling to put out the fire, while elderly patients struggled to escape down the corridor in their wheelchairs.
