At least 25 people were killed and over 107 injured after a fire broke out in a hospital in Jazan in southern Saudi Arabia early on Thursday, according to AFP.

The fire started on the floor where the intensive care unit (ICU) and maternity sections are located in Jazan General Hospital, the civil defence agency said in a tweet.

The injured have been shifted to private and general hospitals in Jazan, BBC reported.

The agency was informed about the fire in the hospital around 2 am (2300 GMT). At least 21 civil defence teams were rushed to the accident site to put out the blaze.

The fire has now been put out and the Saudi authorities have started an investigation. "Jazan hospital accident is now over and investigation is underway to find out its reasons, (sic)" the agency said in another tweet.
