Three military officers participating in the Democracy Day Parade, on Monday, slumped at the Eagle Square in Abuja.
According to reports, there was a bit of confusion as some security and medical personnel rushed to the parade ground with stretchers and whisked the collapsed men to the medical shed.
No casualties were, however, recorded as they were successfully treated and soon regained consciousness.
It was speculated that the officers succumbed to exhaustion having stood for hours on one spot under the scorching sun for the parade.
The ceremony featured performances by the Army, Navy, Air Force and the Police.
In attendance at the annual event were former President Goodluck Jonathan, the Secretary to the Government of the Federation, Presiding Officers of the National Assembly, Service Chiefs, Members of the Diplomatic Corps, Youth Corps Members and former Cabinet Member under President Yar’Adua, Babagana Kingibe.
