4 injured, including 2 firefighters, in Wilmington house fire on Sunday

Four people, including two firefighters, were injured during a house fire in Wilmington, Delaware, on Sunday afternoon, fire officials said.

Fire crews responded to the blaze at around 1:40 p.m. at the  400 block of West 29th Street, officials said.

First responders initially believed two people were still inside the burning home, causing them to go inside to try to rescue them, officials said.

Two firefighters received burn injuries during the search and are in stable condition, officials said.

Although it turned out that the two people who were inside had escaped before the search began, two people were taken to the hospital due to smoke inhalation and their conditions are unknown at this time, officials said.

The home where they fire originated and the adjoining home have been deemed uninhabitable, and the Red Cross is helping people who have been displaced find temporary housing, officials said.
