Two people were killed and at least 20 injured when a group of 3 people fired indiscriminately into a crowd outside a concert hall in Miami, Florida.

The shooting took place early Sunday morning, and the police explained that the hall was hosting a party, and many organizers were standing outside, explaining that a car approached, and "three people got out of it and started shooting randomly at the crowd."

Ambulance teams found two dead people, and transported at least 20 wounded people to hospital, including at least one in critical condition.

The head of the police station, Alfredo Ramirez, condemned in a tweet the "cowardly act of violence with weapons."

And in Florida in 2016, there was a shooting at a nightclub in Orlando, in which a gunman killed 49 people and wounded at least 68.

The frequency of shootings has increased across the United States over the past year, and the country is witnessing frequent shootings targeting schools, offices and malls.

The United States counted more than 43,000 people killed by firearms last year, including suicides, according to the Archives of Gun Violence.
