UPDATE 10:20 a.m.: A video posted on X shows a fire on the side of the building in which the suspect is barricaded:

ORIGINAL STORY: D.C. law enforcement has issued a shelter-in-place order after a mass shooting in our nation’s capital left multiple people injured, with the suspect reportedly barricading himself and defying police.

Breaking 911 initially reported four injured at a VIDA Fitness gym shooting Thursday in Washington, D.C., but has since updated the count to five wounded.

Fox News shared footage of the heavy concentration of police in the area of the shooting, since the shooter is still not in custody as of about 9:50 a.m. Eastern time.

The shooter reportedly barricaded himself in the fitness center.

There were two violent incidents within the last couple of weeks near the White House, one with an armed illegal alien threatening to kill the president and another with a vehicle ramming attack involving the Secret Service.

This is a developing story, and PJ Media will publish more information as it becomes available.
