A lockdown at Fort Lee Army Base in Virginia has been lifted after officials said that a female soldier shot herself.

According to the Associated Press, the unnamed solider entered the building with a gun, which prompted a lockdown Monday morning.

The Wall Street Journal reported that military officials said that sergeant first class brought the weapon to the Combined Arms Support Command headquarters just before 9:00 a.m. She then barricaded herself in an office while negotiators tried to work with her before she turned the gun on herself.

After shooting herself in the head, the 14-year veteran was transported to a nearby hospital. Her condition at this time is not known.

Authorities gave the all-clear about 50 minutes after the active shooting situation was first reported.

Shootings have occurred at military bases in the past. In 2009, 13 people were killed in a shooting at Fort Hood in Texas. In April of this year, an Iraq veteran shot and killed three people and injured 16 more at the same Texas base before shooting himself. And last September, 12 people were killed and four were injured by a government contractor at a Navy Yard in Washington D.C.

Fortunately, there were no fatalities to report after Monday’s incident.
