KANSAS CITY, Kan. (AP) — A young pregnant woman and her 2-year-old son were hospitalized after being wounded when gunfire erupted at a family birthday party in Kansas City, Kansas.

Police say the shooting was reported late Saturday in the city’s Armourdale community. The injured woman and child were in an upstairs bedroom when they were shot from outside the home. The woman lived at the house.

Family members said more than 20 relatives, including several children, were in the back yard of a house when an altercation started in a nearby alley. They say when shots rang out, everybody ran inside the house.

Family members said they don’t know if anyone from the party was involved in the altercation.

They said the wounded victims’ conditions were improving Sunday.
