Three officers were shot Tuesday night while executing a warrant in Kansas City, Missouri, police said. They were in stable condition with non-life-threatening wounds, police said.

The gunfire led to an ongoing standoff at the scene, police added.

It occurred just after 9:30 p.m.

Kansas City Mayor Quinton Lucas tweeted that, “We’ve been reminded too much lately in Kansas City how dangerous police work can be. I am praying for a full recovery for our three officers injured this evening and that everyone on duty gets home to their families safely.”

Betsy Webster, with CBS Kansas City, Missouri affiliate KCTV, tweeted that there was a “large presence of officers” at a local hospital and that the emergency entrance was blocked by crime tape:

She added that the head of the local police union was there and that, “The mood, as you would expect, is tense.”

K.C. police said the investigation is being handled by the Missouri Highway Patrol.
