At least 40 inmates were hurt in a disturbance at the municipal jail in Cancun, a resort city in the Mexican Caribbean state of Quintana Roo, officials said.

Ambulances transported 14 of the inmates, including one in serious condition, to hospitals, the Red Cross said, without providing further details.

Inmates and guards fought Tuesday at the jail, Mexican media reported.

Officials, however, have not confirmed that a disturbance occurred at the facility.

The arrival of coroner's office vehicles at the jail prompted reports of deaths in the riot, but officials have not confirmed any fatalities.

Inmates had complained recently about abusive treatment, strict rules and bad food, relatives said.

The Cancun municipal jail, which holds 1,200 inmates, houses people convicted of common crimes.
