Belgium is observing three days of national mourning. 比利時全國哀悼三天

A woman writes a messages of support on the walls of the Bourse De Brussels building in the Place de la Bourse following yesterday's terrorists attacks on March 23, 2016 in Brussels, Belgium. Belgium is observing three days of national mourning after 34 people were killed in a twin suicide blast at Zaventem Airport and a further bomb attack at Maelbeek Metro Station. Two brothers are thought to have carried out the airport attack and an international manhunt is underway for a third suspect. The attacks come just days after a key suspect in the Paris attacks, Salah Abdeslam, was captured in Brussels. (Christopher Furlong/Getty Images)
