Paris remains on edge nearly 48 hours after seven terrorists killed 132 people and injured hundreds more.
Thousands of people fled the Place de la République after panic spread through the crowd.
Newstalk's Shona Murray was at the scene:
Those who had been singing and mourning the lives lost on Friday scattered, running towards nearby buildings for safety.
Police temporarily sealed off the plaza, but within minutes it was identified as a false alarm.
Channel 4's Jon Snow said that a distant gunshot was heard coming from the direction of La Marais, a nearby area of the city.
