A mother and her two young daughters were killed when a fire ripped through their Brooklyn apartment early Friday, authorities said. 

The 40-year-old mom and her two kids, aged 8 and 10, were found inside the third-floor apartment on Gates Avenue near Tompkins Avenue in Bedford-Stuyvesant, where the fire broke out just after 5 a.m.

All three were taken to Woodhull Medical Center, where they were pronounced dead, police said.

Their names were not immediately released, pending family notification. 

Video from the scene shows an FDNY truck stretching its ladder and a firefighter entering a window – as sirens blare and other fire trucks line the block. 

The blaze was placed under control by around 5:45 a.m. 

The cause of the fire remains under investigation.
