Global markets and U.S. stock futures are falling after several explosions rocked Brussels, the capital of Belgium.
Twin blasts hit Brussels airport early Tuesday. They were followed by an explosion in a subway station in the city.
At least 23 people were killed, according to Belgian media, 10 at a subway station and at least 13 at the airport.
Brussels is the de-facto capital of the European Union. Many European institutions and international companies are based there. The airport is closed, and train and subway services have been suspended.
Here are the four things you need to know before the opening bell rings in New York:
1. International market overview: U.S. stock futures are down. All European markets opened lower following the explosions in Belgium.
France’s CAC and Germany’s DAX indexes are down by nearly 1%, and the FTSE in the U.K. is slipping. Asian markets closed the session mixed.
