An official says shots have been reported in a building on the Washington Navy Yard campus.

Navy spokesman Petty Officer 1st Class Pedro Rodriguez says a lockdown is underway.

He did not give information on injuries or other details Thursday morning.

In September 2013, military contractor Aaron Alexis killed 12 civilian workers at the Navy Yard's Building 197 before he was fatally shot by police.

The Navy Yard, in southeast Washington, is the country's oldest naval installation.
