A heartwarming story is emerging after the attack in Nice, France, that left 84 people dead and many others injured during Bastille Day festivities last week. A family lost track of one another in the carnage following the attack but was reunited the next day because posts appealing for help went viral on Facebook.

A truck driven at high speed by a suspected terrorist plowed through crowds gathered to watch fireworks on the Promenade des Anglais, causing chaos. In the confusion, a woman lost track of her young child. The mother's friends quickly turned to Facebook for help, posting requests for assistance to the social media site that evening.

"If you see this child: CONTACT ME," wrote Yohlaine Ramasitera in French, posting a photo of herself and the unnamed toddler, along with her phone number and information that he was in a blue stroller. The photo was shared by another individual, Rebecca Boulanger, along with an appeal that quickly went viral:

"VERY IMPORTANT: in the rush of things with shots being fired some friends of our friends lost their baby boy !!! a 8-10 month old beautiful baby"

Boulanger, a friend of Ramasitera's, spoke with The Huffington Post about the incident: "I couldn't do much because I was at home with my own baby. But because I’m a pastor, and I grew up in Nice, I decided to use my large social network to help."

Boulanger said that she received news about two hours later from an unrelated woman, who said that she had taken the young boy in and that he was safe. The pastor then shared the news on Facebook that the boy had been located and would soon be reunited with his family.

"I was very relieved," Boulanger later told The Huffington Post.
