Police say the gunmen opened fire yesterday in the Denham Town neighbourhood just west of the capital of Kingston. Police say most of those shot are women.
Authorities blame the shooting on gang members fighting to control territory once run by Christopher Coke.
The former gang leader was sentenced in a New York court in 2012 to 23 years for drug trafficking and is now in a South Carolina prison.
Police say 11 people are recovering from their injuries at a hospital. No one has been arrested.
