Many Belgians are using the hashtag #IkWilHelpen, or "I want to help," on Twitter, Facebook, and other social media platforms, to offer people places to rest or stay or to get ride shares around the region.
This comes after attacks on the Brussels airport and Metro system this morning, which have led to many deaths and injuries.
The spontaneous upswing of neighborliness echoes the #PorteOuverte hashtag, which means "open door" and which was widely used on social media during the aftermath of the Paris attacks last November.
The Belgian public transport system is under lockdown in the wake of the attacks and many people were unable to get home.
Offers of car rides are the most common volunteer good, especially from people living near the temporarily closed airport.
