Fire brigades rushed to the scene of the blaze at the religious school in the Jalan Datuk Keramat area early on Thursday morning.
Nine fire engines from four stations rushed to the scene alongside the Klang river, with the wounded being taken to the Kuala Lumpur Hospital.
The school is believed to be for Islamic students in the region, with the blaze breaking out at approximately 5.15am.
It is currently unclear if the learning establishment was a boarding or semi-residential school.
A fire and rescue spokesperson said: “Based on our information at the moment, 25 students and teachers have died in the fire.
“Our personnel are still at the scene.”
It follows concerns over the safety of religious schools in the country, with 211 fires breaking out since 2015.
The horrifying death toll could rival the tragic 1989 blaze in Kedah, where 27 students at an all–girls school were killed after a blaze broke out and spread to eight nearby wooden hostels.
