NEW HOPE, MN (KTRK) -- A gunman opened fire inside a suburban Minneapolis city building Monday night, injuring two police officers before authorities returned fire and killed him, the county sheriff's department said.



The terrifying moments were caught on video inside the city council chambers. Video shows the city council memberse duck under the desk when they heard gunfire. One of the city council members even draws his own weapon, prepared to defend himself if needed.



Hennepin County Sheriff's Office chief deputy Mike Carlson said the shooting happened around 7:15 p.m. while two officers were being sworn in at the New Hope City Hall.



The newly sworn-in officers and others were leaving the city council chambers when they encountered a man armed with a "long gun," Carlson said at a news conference.



The man opened fire and struck two New Hope police officers, Carlson said. Other officers immediately returned fire, killing the gunman, he said.



Carlson said the officers are in good condition and are expected to survive. He did not identify the gunman or disclose a possible motive for the attack, the St. Paul Pioneer Press reported.



Police say they do not know why the gunman ambushed the officers. Investigators have not yet made the shooter's name public.
