MIAMI (AP) - Authorities in Miami-Dade County say police shot and killed four suspects during a confrontation after they got out of their vehicles wearing ski masks and carrying guns.

Miami-Dade Police spokesman Alvaro Zabaleta says the robbery bureau was investigating Thursday evening in the southwestern section of the county when they learned of suspicious activity.

Several suspects were identified and due to their criminal history, Zabaleta says the department's special response team was called in.

According to Zabaleta, the suspects arrived in the area wearing ski masks and carrying guns. A confrontation occurred as the men got out of their vehicles. Shots were fired and four suspects were killed.

Zabaleta says none of the police officers was injured.
