At least three persons collapsed at the 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 colorful parade, presided over by Muhammadu Buhari, was well underway 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 unclear if they were able to return to their duty beats for the continuation of their duties.
