Belgians turn to Twitter to offer rooms, rides

Brussels residents turned to Twitter to offer people stranded in the Belgian capital rooms and transport after the attacks. A new Twitter account called "Brussels Lift" was created to offer practical help by connecting "people who need to travel with drivers who have empty seats". No trams or buses were running and some people walked long distances across the city to get home. Facebook also activated its "safety check" feature after the attacks, enabling users to reassure friends and relatives.
