World markets and U.S. futures were declining Tuesday following a terrorist attack in Belgium that killed at least 26 people and injured 130.
Authorities confirmed that a suicide bomber committed an attack at the city's main airport with two bombs exploding near the check-in area at about 8 a.m. An hour later, another bomb exploded at a subway station near the European Union headquarters.
The attacks come just days after Belgian authorities arrested Salah Abdeslam -- the last remaining suspected participant in the Paris terror attacks last year -- in Brussels on Friday. The explosions disrupted travel at the two travel hubs.
