Three people were hospitalized after a fire tore through four row homes on the same north Baltimore block where a pride flag was burned early Wednesday, officials said.

Thousands gathered in Baltimore on Wednesday to mourn the loss of three firefighters who died after they were trapped in a burning vacant rowhome when it partially collapsed last week.

Three Baltimore firefighters were killed and a fourth was injured when part of a vacant home collapsed while they were battling a blaze early Monday, the city's fire chief said.
