Thousands of people are using the hashtag #jesuisbruxelles to show solidarity with Brussels and the dozens of people killed or wounded in today's deadly terror attacks. Repeating the French 'Je suis' phrase that became a hallmark of support for France in the wake of the Charlie Hebdo attacks, some 80,000 people have now used it to send their support to Belgium. Many of these are in the form of illustrations or cartoons in the Belgium national colours next to the French tricolour.
