Officials lifted a lockdown today at Davis-Monthan Air Force base in Arizona that was prompted by unconfirmed reports of gunshot sounds.

They later said in a news release that reports of gunshot sounds were unconfirmed.
Two schools are also inside the base. Both said all students were safe and unaccounted for.About 10,500 people work on the Tucson base. The base is home to the 355th Fighter Wing, which provides training and deploys the A-10 jet.
