The SWAT agents were with ICE's Homeland Security Investigations and were transported to a hospital with injuries that were not life-threatening, agency spokeswoman Virginia Kice said.
One suspect was taken into custody, Kice said.
Residents reported hearing gunfire around 4am and two helicopters in the area.

At the Best Western, guests were told to stay in their rooms, although they were allowed to leave their rooms shortly after 6 a.m., according to the manager.
Several people were taken away in ambulances, and one was airlifted from the area.
"We'd always see undercovers (undercover agents) sitting outside," said Sadie Vega-Martinez, who lives in the area. "They brought several people out...but then they still wouldnt go in and used a megaphone in English and Spanish asking them to come out. They used chainsaws and things to get in... They were nice neighbors...never would have known!"
