At least three military officers collapsed at Eagle Square during the military parade to mark the Democracy Day ceremony on Monday.
Those who collapsed during the parade were believed to be members of the different units of the military, who had been on their feet hours before the commencement of the event.
The colourful parade, presided over by President Muhammadu Buhari, was already in motion when a bit of commotion broke out from behind one of the parties as some security and medical personnel were seen scrambling stretchers to move those who had collapsed for urgent medical attention.
They were rushed to the tents provided at the square for medical personnel where physicians successfully resuscitated them.
It was not clear whether they were able to return to their duty beats for the continuation of their duties.
On arrival, President Muhammadu Buhari inspected the parade immediately and was followed by a military/police march past in a slow and quick time.
The event also involved a combat march display by the Nigerian Army Women Corps as well as the combined silent drill display by the Armed Forces and Police.
It further featured a Democracy Day playlet, a cultural troupe display, showcasing Nigeria moving forward from the six geo-political zones.
Also on display were the combined band/silent drill display by the armed forces and advance in review order.
President Buhari also signed the anniversary register, followed by the parade commander leading three hearty cheers.
