Two people suffered smoke inhalation injuries Thursday night when a fire broke out in an Oxon Hill apartment building, and firefighters rescued a woman in her 60s, Prince George’s County fire officials said.

Firefighters responded to a blaze in the 2100 block of Alice Avenue and found fire in a second-floor unit about 6:30 p.m., said Mark Brady, a fire department spokesman.

Firefighters pulled the woman from an apartment and she was taken to a hospital in critical condition with apparent smoke inhalation, Fire Chief Marc Bashoor said in a tweet.

A man, also in his 60s, sustained smoke injuries and was taken to a hospital in serious condition.

A third person was evaluated by medics at the scene. The cause of the fire is under investigation, Brady said.
