Two children, including an infant, are in critical condition after a fire broke out in their Brooklyn apartment building Wednesday morning.

Sixteen people, including six firefighters and at least two children, were injured in an early morning fire at a Brooklyn apartment building, the FDNY said. The fire started just after 6 a.m. in a seven-story building at 65 Bay 19th Street in the Bath Beach area,

Tenants in the apartment where the blaze broke out left their fire-proof door open and so flames quickly spread and smoke filled the hallways.
