(CNN) -- A fire killed six people in Baltimore, Maryland Tuesday morning, authorities said.
The blaze at a two-story home in East Baltimore was reported just before 5 a.m., said Kevin Cartwright, a Baltimore Fire Department spokesman.
Firefighters entered the home but had to evacuate because of the fast-moving fire. After extinguishing the blaze, firefighters entered the home again and found five bodies. A sixth victim was found later, Cartwright said. Some of the victims were children, he said, but did not give a number. The relationship between the victims was unknown.
Authorities were still trying to determine if the home had working smoke alarms and what caused the blaze, Cartwright said.
Firefighters had completed a search of the structure as of about 7:30 a.m., he said.
