Belgium Mourns After Deadly Brussels Terror Attacks

BRUSSELS, BELGIUM - MARCH 23: Belgian soldiers stand guard outside of the closed Brussels Zaventem airport 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. (Photo by Adam Berry/Getty Images)
