WARSAW, Poland (AP) – Polish prosecutors are raising the death toll from a fire that ripped through a homeless shelter in mid-April to 23 after DNA tests on the victims.

Malgorzata Wojciechowicz, a spokeswoman for prosecutors in Szczecin, said Thursday that 23 people were killed in the blaze, including 13 children.

Officials initially said 21 people died. However, many of the remains were charred, making identification difficult. An additional 20 people were injured.

The blaze ripped through a three-story shelter for homeless families in the northwestern town of Kamien Pomorski on April 13. Authorities say local inspectors allowed people to live in the building despite code violations.
