U.S. airlines including Delta, United and American rerouted and canceled flights on Tuesday following two deadly blasts that shut down the Brussels Airport at Zaventem.

A suicide bomber blew himself up at the airport on Tuesday morning, killing at least 11 people, according to the Belgian health minister. At least another 15 were killed when a blast tore through a rush-hour metro train in the European capital shortly afterward, the city’s transport operator said.

Delta Air Lines Inc said its flight DL42 from New York to Brussels was diverted to Amsterdam. Another flight, DL80 from Atlanta, had landed safely at the Zaventem airport and was parked remotely while the airline’s local staff helped passengers exit safely.

News of the multiple blasts, which have Brussels on lockdown, sent shares of U.S. airlines and travel-related companies lower in premarket trading. Delta was down 3 percent, while United Continental Holdings Inc fell 1 percent.

United Airlines, which had two flights due in Brussels on Tuesday morning, said both safely arrived.

United said all remaining flights to and from Brussels International were suspended until further notice.
