Police said 20 people were hurt in the incident.

Miami-Dade police director Alfredo Ramirez III tweeted: "I am at the scene of another targeted and cowardly act of gun violence, where over 20 victims were shot and 2 have sadly died. These are cold blooded murderers that shot indiscriminately into a crowd and we will seek justice. My deepest condolences to the family of the victims."

Alfredo Ramirez III described those behind the attack as 'cold blooded murderers'.  

A white Nissan Pathfinder pulled up to a billiards club in Hialeah between 12 a.m. and 1 a.m., Ramirez was quoted as saying by CNN.

Three people got out with assault weapons and handguns and started firing into the crowd that was gathered for a concert at the venue, he said.
