The main gate at F.E. Warren Air Force Base was closed Wednesday afternoon.

Lieutenant Veronica Perez with the 90th Missile Wing Public Affairs Office confirmed the closure, but couldn't say what prompted officials to close the gate.

"We don't know exactly what happened. They were responding to something, but we don't know what," said Lieutenant Perez. "It was closed, and I'm not for sure how long it was closed, but it is open now."
