When a fire broke out Thursday at a senior citizens apartment building in Washington, D.C., about 100 Marines came running to help, according to a report.

The Marines, stationed just a half-mile away, took action after they saw smoke pouring from the building, Washington’s Fox 5 reported.

A video posted to Twitter (embedded in the video below) captured the moment as the Marines sprinted toward the blaze to assist Washington, D.C., firefighters and paramedics.

“Marines rushed into the building to rescue those who needed assistance and evacuated residents to the Marine Barracks Washington Annex, where they were checked and treated for any injuries and sheltered until their loved ones arrived,” Marine Barracks Washington 8th & I said in a statement on Facebook.

The cause of the blaze was not immediately clear, fire officials said.

Four people were transported to nearby hospitals with minor injuries, according to officials.
