Three military officers participating in the Democracy Day Parade slumped at the Eagle Square, Abuja.
The incident happened on Monday and it is believed the officers succumbed to exhaustion having stood for hours on one spot under the scorching sun.
According to sources, some security and medical personnel rushed to the parade ground with stretchers and whisked the collapsed colleagues to the medical shed on the left side of the State Box where President Muhammadu Buhari was seated.
However, no casualties were recorded as they were successfully treated and soon regained consciousness.
The ceremony featured performances by the Army, Navy, Air Force and the Police.
