Two people were killed and at least 20 more wounded after three gunmen opened fire indiscriminately into a crowd at a billiards club in the southeastern U.S. state of Florida early on Sunday, local authorities said.

The mass shooting happened during the early hours at a billiards hall on a commercial estate near Miami Gardens, to the northwest of the coastal city's downtown. 

Three people jumped out of an SUV with assault weapons and handguns and started firing into the crowd that gathered for a concert at a billiards club in Hialeah city between 12 a.m. (0400 GMT) and 1 a.m., Director of Miami-Dade Police Department Alfredo Ramirez III said.

The venue was "hosting a scheduled event and several patrons were standing outside," Miami-Dade Police Department said in a statement. 

"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," Ramirez tweeted.

Two people were pronounced dead at the scene, and 20 to 25 victims were rushed to hospital, he said.

It was the second mass shooting in the city in little more than 24 hours. On Friday, another shooting in Miami's Wynwood district left at least one person dead and six others wounded.
