The fire, which broke out on the second floor of the Sultanah Aminah Hospital early morning, forced the mass evacuation of hundreds of patients and medical staff.

Malaysian Prime Minister Najib Razak tweeted that the government will conduct a thorough investigation as soon as possible to identify the cause of the fire and the safety level.
