NEW HAVEN, Conn. (WTNH) — A three-alarm fire displaced seven people early Monday morning in New Haven.

The fire broke out at 706 Dixwell Ave around 1:30 a.m. The building houses Dix Deli on the first floor and apartments on the second and third floors.

According to New Haven’s fire chief, the fire appeared to have started on the roof, and it took some time for firefighters to put the fire out due to the number of coolers blocking access to the fire growing in the walls.

The building suffered extensive damage, displacing four children and three adults. The Red Cross is assisting them with housing.

Dixwell Avenue was closed, but it has since reopened.
