Two police officers in the Des Moines metro-area were shot and killed in apparent "ambush-style" attacks early Wednesday.

Police from Urbandale and Des Moines responded to a report of gunfire at the intersection of 70th Street and Aurora Avenue about 1:06 a.m. CT (2 a.m. ET).

The first officers arriving on the scene found an Urbandale officer shot in a car. The officer, whose name was not released, died, said Des Moines Police Sgt. Paul Parizek in a news release.

At about 1:26 a.m., a Des Moines police officer was shot and killed in a car near the intersection of Merle Hay Road and Sheridan Drive. The officer's name was not released.

Police were still notifying the family members of the slain officers early Wednesday and planned to withhold the officers' names, years of service and other details until later in the day, Parizek said.

At an early morning news conference, officials said police service will not change in either Des Moines or Urbandale but, as a precaution, officers on patrol have been paired up.

"We're always vigilant about our safety, but we've still go to go out there," Parizek said.

For Des Moines, this is the first police officer shot and killed in the line of duty since two officers were gunned down in separate incidents in 1977.

Two Des Moines officers, Susan Farrell and Carlos Puente-Morales, also died earlier this year when their vehicle was struck head-on by a wrong-way drunk driver.
