Cuban prosecutors are seeking six- to 14-year prison terms for workers at the island's largest hospital for the mentally ill, where 26 patients died during a cold snap.

State-run newspaper Granma says the trial has concluded but no verdict has been announced.

Temperatures in normally balmy Cuba plunged below 38 degrees Fahrenheit (4 Celsius) in January 2010 in the area where Havana's Psychiatric Hospital is located.

Human rights leaders cited negligence and a lack of resources as factors in the deaths, and the Health Ministry began an investigation.

Granma said Monday that prosecutors asked for six to 14 years for several officials, including the hospital director, and 10 to 12 for other defendants accused of embezzlement.
