Under the hashtag #PorteOuverte (Open Door) and #ikwilhelpen (I Want to Help), people have been tweeting out offers of shelter for anyone in need.
Drivers have also offered stranded commuters a lift after train service was suspended. One Twitter user posted a tweet in French -- one of the main languages spoken in Belgium -- stating that she has four available spots in her car for anyone who is stuck in Brussels. Others formed emergency carpools to get people where they needed to go.
Twitter user Dennis Covent tweeted a photo of himself with some passengers he ferried from Brussels to their home in Antwerp.
The outpouring of support on social media extends far beyond Belgium, with people around the world posting messages of solidarity under the hashtag #JeSuisBruxelles (I am Brussels) -- inspired by the #JeSuisCharlie campaign that went viral after the terrorist attacks in Paris last year.
