Firefighters are searching for six children that are unaccounted for after an early morning fire engulfed the family home in northeast Baltimore.
Baltimore City Fire Department spokesman Roman Clark said firefighters arrived to see large flames coming from all three floors.
Firefighters say they have received reports of children trapped in the rubble following a collapse inside of the building.
It remains unclear what sparked the fire in the early hours of Thursday. He says the woman and two of the children are in critical condition and the third child is in serious condition.
Authorities said the rescued woman is believed to be the mother of all nine children.More news: Ret. Gen. James 'Mad Dog' Mattis set for Defense confirmation hearing
He said he had not been at home during the blaze as he was working at a restaurant.
U.S. Rep. Elijah Cummings' office identified the woman injured as one of his staff members. Clark said the department was waiting for additional equipment to arrive on the scene to continue to search for the missing children. He said he does not know what may have caused the fire.
Maryland Representative Elijah Cummings identified the mother as Katie Malone, a special assistant who had worked in the congressman's office for almost 11 years, according to a press release from his office. My staff is a family and this unimaginable tragedy is shocking and heartbreaking to us all.
Mr. Malone said he is "still in shock" about the fire. Several floors of the home had collapsed in the heavy fire, according to Clark.
