Police say four children are among the 12 people killed in New York City's deadliest residential fire in decades.
Mayor Bill de Blasio said Friday on CNN that other people are still fighting for their lives. The Democrat says first responders saved at least 12 lives.
The New York Police Department says those who died in the Bronx fire Thursday night include girls ages 1, 2 and 7, and a boy. His age was not given.
Some residents made it down fire escapes. But the flames moved so fast that many never made it out of their apartments.
Witnesses describe seeing burned bodies being carried away on stretchers and young girls who had escaped standing barefoot outside with no coats.
The cause of the fire remains under investigation.
