Cuban authorities are investigating the deaths of 26 patients at a psychiatric hospital linked to a spell of unusually cold weather.

Human rights activists blamed the deaths on negligence and the dilapidated state of the hospital.

Cuba prides itself on its provision of free universal healthcare.

The deaths occurred at the Psychiatric Hospital in the capital, Havana, which houses some 2,500 patients.
